Convert Image — free, in your browser
Change PNG, JPG and WebP into one another without uploading anything or adding a watermark.
To convert an image, drop it here and choose PNG, JPG or WebP. WebP is the best default — every current browser supports it, it keeps transparency and it is 25–35% smaller than JPG. Converting to PNG is lossless; to JPG or WebP is not. Nothing is uploaded.

How it works
- 1
Add your images
Drag them in or click to browse. The format is detected from the file's own contents, so a mislabelled extension won't trip it up.
- 2
Choose the output format
PNG for transparency and lossless quality, JPG for the widest compatibility, WebP for the smallest file at the same visual quality.
- 3
Convert and download
Each converted file appears here with its new size, ready to download straight away.
What each setting does
- WebP
- The right default for almost everything on the web. Supported since 2020 by every current browser, keeps transparency like PNG, and compresses far better than either PNG or JPG. The only real gap is older desktop software and some email clients.
- PNG
- Lossless, so nothing is discarded and the result is pixel-identical. Right for logos, icons, diagrams and screenshots containing text, where a stray artefact around a hard edge would show. Expect the file to grow if the source was a photograph.
- JPG
- Widest compatibility, and the safest thing to hand to unknown software. Cannot store transparency at all — any transparent area becomes solid, usually black or white, and there is no way back.
- Quality
- Only appears for JPG and WebP, because PNG is lossless and a quality control there would be a lie. 82 is a good default; raise it for images with text or gradients.
Results you can expect
Measured on real files by our own test suite, not estimated.
| Convert to | Typical change | Note |
|---|---|---|
| WebP, quality 82 | 80–90% smaller | Best size at matched quality |
| JPG, quality 82 | 75–85% smaller | Widest compatibility, no transparency |
| PNG | 20–35% smaller | Lossless re-encode, nothing discarded |
What people use this for
PNG to WebP for a website
Usually halves a screenshot and does far better on photographs, with no visible difference. The single easiest performance win most sites have available.
Read the guideJPEG to PNG for editing
Every JPG save re-compresses and compounds damage. Converting to PNG first means repeated edits cost nothing, though the file will grow.
Read the guideChoosing between formats
Which format to use is the question behind most conversions, and the answer depends on transparency, text and where the file is going.

Questions
Does converting upload my images anywhere?
No. Conversion runs in your browser with WebAssembly. Your images are read from disk into memory on your own device and are never transmitted. Open your browser's network tab while converting and you'll see no requests at all.
Should I convert PNG to JPG?
Only if the image has no transparency. JPG cannot store an alpha channel, so any transparent areas become solid — usually black or white. For photographs without transparency, JPG or WebP will be far smaller than PNG. For logos, screenshots and anything with transparency, stay on PNG or use WebP.
What is WebP and can I use it?
WebP is a modern format supported by every current browser, including Safari since 2020. It typically produces files 25–35% smaller than JPG at the same visual quality and, unlike JPG, it supports transparency. The main caveat is older desktop software, some of which still can't open it.
Will converting lose quality?
Converting to PNG is lossless, so nothing is discarded. Converting to JPG or WebP is lossy and does discard some data, though at the default quality the difference is very hard to see. Converting a JPG to another lossy format twice compounds the loss, so work from the original where you can.
Can I convert several images at once?
Yes. Add as many as you like and they're converted one after another, each appearing with its own download button. There is no cap on how many, because the work happens on your device rather than on a server we pay for.
Why is my converted file larger than the original?
Converting a lossy format to a lossless one usually grows the file, because PNG has to store every pixel exactly rather than approximating. Going from JPG to PNG will almost always produce a bigger file. If size matters more than exactness, convert to WebP instead.
Does converting change the image dimensions?
No. Converting changes how pixels are stored, not how many there are. Use Resize Image if you also need different dimensions.
Will converting to PNG improve a low-quality JPG?
No, and this is a common misunderstanding. PNG preserves whatever it is given perfectly, including the JPG's existing artefacts. The damage happened at the first encode and cannot be undone by a later conversion.
What happened to my EXIF data?
Conversion drops metadata such as camera settings, dates and GPS coordinates. That is often desirable when sharing, since embedded location data is more revealing than most people realise, but keep your original if you need it.
Is AVIF supported?
Not currently. Its encoder is significantly slower than the others, painful on phones, and the library ships an 8 MB codec that we chose not to put in front of every visitor. WebP gets you most of the benefit at a fraction of the cost.
Which format is best for a website?
WebP for nearly everything. PNG only for logos, icons and screenshots with text where lossless output genuinely matters. JPG only when something downstream cannot read WebP.
If something looks wrong
- The converted file is larger
- You converted a lossy format to a lossless one. PNG stores every pixel exactly rather than approximating, so a JPG converted to PNG will almost always grow — often several times. If size matters more than exactness, convert to WebP instead.
- Transparency disappeared
- You converted to JPG, which has no alpha channel at all. The transparent area is filled with a solid colour and cannot be recovered from the output. Convert from the original to PNG or WebP instead.
- Text looks fuzzy after converting
- Lossy formats handle hard edges worst, and letters are all hard edges. Raise the quality above 90, or use PNG for anything that is mostly text — a screenshot converted to JPG at default quality shows visible fringing around every character.
- Something will not open the WebP
- Browser support is universal, but some older desktop software and email clients are not. Convert to PNG or JPG for those specific destinations rather than avoiding WebP everywhere.
