JPG to PNG Converter
Convert JPG files to PNG in seconds: one file or a whole batch, downloaded as a ZIP. Images never leave your device; the conversion runs in your browser. PNG is lossless, so further edits add no new quality loss.
JPGAny other image works too; the tool detects it
Converted on your device; never uploaded.
PNG is lossless, so there is no quality setting. The image is kept pixel for pixel; the file usually gets bigger.
PNG and WebP keep transparency; no background is added.
- JPGNo transparency · lossy · most compatible for photos
- PNGTransparency · lossless · logos, text, screenshots
- WebPTransparency · smallest files · websites
You can drop several files at once. Change a setting and the list converts again automatically.
Result
Up to 100 files · you can also paste (Ctrl/Cmd+V)
Your browser cannot save WebP. Please try Chrome, Edge or Firefox.
Which conversion do you need?
Every conversion has its own page; the same tool opens with those formats selected. Not sure about the source format? Use the general converter, it detects the file itself.

JPG to PNG in 4 steps
- Add your files
Drag the JPG files onto the panel, pick several with Choose images, or paste with Ctrl/Cmd+V. You can add up to 100 files at once.
- Check that the target is PNG
On this page the Target format comes preset to PNG. You can switch to JPG or WebP whenever you like, and because PNG is lossless, the quality slider stays hidden for it.
- Review the rows
Each row shows a small preview, the name, the Detected format, a JPG → PNG label, the size before and after, and the percentage change. Also, a bigger file is normal for this conversion.
- Download one by one or as a ZIP
The Download button on a row gives you a single file, while Download all as ZIP bundles everything. If you change a setting, the list converts again by itself.
What to expect when you convert JPG to PNG
This table shows the rough direction, because the tool calculates the exact result for each file in its own row. We give no numbers here, since file size varies a lot with the content of the picture.
| Source JPG | What happens as a PNG | Our advice |
|---|---|---|
| Phone or camera photo | It looks the same, but the file grows noticeably. | Convert only for a working copy or for a form that demands PNG. |
| Screenshot saved as JPG | Smudges around text stay, and the file usually grows. | Take future screenshots as PNG from the start. |
| Flat colour logo or drawing | Flat areas compress well in PNG, so the size can shrink or grow depending on the content. | Try it and read the change percentage in the row. |
| Image you will edit over several rounds | No new loss appears, but the file grows. | Keep PNG as the working copy, then export JPG or WebP at the end. |
| File you saved as JPG many times | The earlier damage is permanent, and PNG cannot undo it. | Go back to the first original if you can. |
| File with the wrong extension, such as a WebP named .jpg | The tool reads the content, detects the real format and writes a true PNG. | Check the Detected format label. |
We left invented ratios out of the table, because the tool's own row is more reliable. In every case, keep the original JPG.
Should you switch to PNG or stay with JPG?
This decision table covers the situations we meet most often.
| Situation | Decision | Reason |
|---|---|---|
| Photo on a website | JPG or WebP | PNG often makes a photo needlessly heavy and slows the page. |
| Email attachment or chat message | JPG | A small file is enough, and PNG usually comes out bigger. |
| Upload field accepts only PNG | PNG | The format is a requirement, so you have to convert. |
| Working copy for several rounds of editing | PNG | Each save no longer adds a new JPG loss. |
| Graphic with text or an interface screenshot | PNG | Sharp edges stay the same in later saves. |
| You need a transparent background | Converting alone is not enough | JPG carries no transparency, so you need an editor that removes the background. |
For the web there is a third option. According to Google's WebP page, lossy WebP is 25-34% smaller than a comparable JPEG at equivalent quality.
What does JPG to PNG conversion actually do?
JPG to PNG conversion turns a file with lossy compression into a file with lossless compression. The tool opens the JPG's pixels and writes them again as a PNG, exactly as they look. The picture stays the same, and only the file format changes.
Here is how it works in short:
- You drag your files onto the panel, choose them with Choose images, or paste with Ctrl/Cmd+V. Up to 100 files fit in one batch.
- The tool reads the first bytes of each file instead of trusting the extension, then shows the result in the Detected format field.
- Target format comes preset to PNG on this page, and you can switch to JPG or WebP at any time.
- Pixel dimensions stay the same. To change them, you need the image resizer.
Everything happens in your browser. Once the page has loaded, your files never leave your device, reach no server and stay nowhere. For example, our team also uses this kind of conversion when a client's site has a mix of image formats.
When is JPG to PNG conversion actually worth it?
Turning every JPG into a PNG is usually pointless. Still, four situations make the switch useful.
- An upload field that accepts only PNG: Some forms, app icon slots and logo fields ask for PNG. Check the requirement in that system's own guidelines, then convert.
- A working copy: When you crop a picture, add text and fix the colours, every JPG save adds another round of lossy compression. So a PNG working copy stops that build-up.
- Text and sharp edges: Text, lines and interface screenshots collect smudges around the edges in a JPG. MDN's format guide also recommends lossless encoding for screenshots, diagrams and logos.
- Print and platform rules: Some print shops and upload systems demand PNG. Ask your printer or read the platform's help page first.
One point needs clearing up early: PNG does not store layers. If you need layers, use the project format of your editing app, and treat PNG only as a flat intermediate copy.
Does JPG to PNG conversion restore lost quality?
No. A JPG throws away part of the picture for good when it saves. That detail no longer exists in the file, and PNG cannot rebuild it.
PNG compresses without loss, so it keeps the incoming pixels exactly as they are. However, those incoming pixels are already the damaged version from the JPG. In other words, the conversion freezes the damage and does not repair it. So do not expect these results:
- Blur, blocks or smudgy halos in the source look the same in the PNG.
- A small image does not grow or sharpen just because it became a PNG.
- Lost detail never returns, because only the first original from your phone, camera or design file holds the true quality.
Your gain is simple: if you open the PNG and save it again, no new loss appears. Still, the idea that a blurry photo gets sharp as a PNG is a myth. Sharpening is a separate job that needs separate software, and a converter does not do it.
Why does a PNG come out bigger than the JPG?
Because a JPG throws away some detail on purpose, while a PNG discards no pixel at all. Photos contain many soft gradients, noise and texture. That kind of content compresses poorly without loss, so the file usually grows.
However, the opposite can happen too. Flat colour areas and graphics with few colours compress well as PNG, so some logos and drawings come out smaller than their JPG. In other words, the content decides, not the format.
That is why each row shows the size before and after plus the percentage change. A rise on a photo is not a bug. If the size bothers you, you have two options:
- Leave the photo as a JPG and convert to PNG only when you truly need it.
- For the web, try the JPG to WebP converter instead. According to Google's WebP page, lossy WebP is 25-34% smaller than a comparable JPEG.
Does the background turn transparent after conversion?
No. A JPG carries no transparency, so its background consists of solid pixels. PNG supports transparency, but the tool does not invent a new transparent area. For example, a JPG with a white background becomes a PNG with a white background.
Removing a background is a separate job. After converting, you need an editor or background removal software to make the selection. Then PNG is the right container for that result, but it does not produce the result itself.
There is also a detail in the other direction. If you switch the target to JPG, the Colour for transparent areas option appears, and you pick White, Black or a custom colour. Because the target here is PNG, you do not need that option. To turn a transparent PNG into a JPG, see the PNG to JPG converter.
What happens to your file, its orientation and location data?
Your file stays inside your browser. The tool sends nothing to a server and stores nothing.
- Orientation: The tool applies the EXIF orientation, so a sideways phone photo comes out upright.
- Metadata: The tool does not carry EXIF data or GPS location into the PNG. That is a privacy advantage, because the file you share does not reveal where you took it.
- Honest note: However, useful details such as the capture date and camera model disappear as well. If you need them for an archive, keep the original JPG.
- Size: Pixel width and height do not change.
The tool also opens inputs other than JPG: PNG, WebP, GIF, BMP, AVIF and other formats your browser knows. Only a supporting browser such as Safari can open HEIC, and the tool says so when it cannot. For animated GIF and WebP, only the first frame converts, so the tool warns you.
When should you stay with JPG?
If you publish photos, you should usually stay with JPG. On a website especially, a large hero photo saved as PNG slows the page. That in turn hurts visitor experience and Core Web Vitals scores.
Stay with JPG in these main cases:
- Website, blog and online shop product photos. We covered the details in our guide to optimizing images for website speed and SEO.
- Email attachments and chat messages, because small files travel fast.
- Large photo archives, especially when your storage runs short.
Google Images supports JPEG, PNG and WebP, among other formats. So changing the format alone is not a ranking move, because the real effect comes from page speed.

Common mistakes when you convert JPG to PNG
- ✕MistakeExpecting PNG to repair a bad JPG✓Do this insteadIt does not. PNG cannot produce the detail a JPG already lost, and only the first original file keeps the true quality.
- ✕MistakeTurning every photo on the website into a PNG✓Do this insteadThe page gets heavier. Keep photos as JPG or WebP, and save PNG for transparency or sharp graphics.
- ✕MistakeExpecting a transparent background after converting✓Do this insteadA JPG has no transparency, so the background stays solid. Removing it takes a separate background removal step.
- ✕MistakeRenaming the extension to .png by hand✓Do this insteadChanging only the name does not change the format, so the content stays JPG. Run the file through the tool for a real conversion.
- ✕MistakeDeleting the original JPG✓Do this insteadKeep the original. Going from PNG back to JPG adds a new loss, and metadata such as location and date has already gone.
