Drop images here, or paste a screenshot
JPG, PNG, and WebP · up to 20 files · no HEIC, nothing uploaded
How to use the image converter
Swap formats without an upload: PNG screenshots to JPG for email, photos to WebP for a website, WebP downloads back to PNG for software that refuses to open them. Drop a batch and convert the lot.
Add the files
Drop, browse, or paste. JPG, PNG, and WebP in — up to twenty at once.
Pick the output format
JPEG for photos and email, PNG when you need transparency or crisp text, WebP for the web at a smaller size than either.
Download
Each card shows the size before and after, so a conversion that makes the file bigger is obvious before you save it.
About this tool
Format choice comes down to three questions: does it need transparency, is it a photograph, and who has to open it. Transparency means PNG or WebP. Photographs mean JPEG or WebP. Unknown recipients mean JPEG, still the safest thing to attach to an email.
Converting is not the same as compressing. Going from PNG to JPEG usually shrinks a photo dramatically, but going from JPEG to JPEG through any converter re-encodes it and loses a little more each time. Convert once, from the original, and keep that original.
Frequently asked questions
- Can you convert HEIC from my iPhone?
- No. HEIC needs a decoder that most desktop browsers do not ship, and a tool that half-works on some machines is worse than one that says no. Set your iPhone to “Most Compatible” under Camera → Formats to get JPGs at the source.
- Why did my PNG get bigger as a PNG?
- It did not — converting PNG to PNG is a no-op here. If a JPG grew when you converted it to PNG, that is expected: PNG is lossless, so it stores every JPEG artefact faithfully and costs more to do it.
- What happens to transparency?
- PNG and WebP keep it. JPEG has no alpha channel at all, so transparent areas are flattened onto white — deliberately, because the alternative is black boxes.
- Is WebP safe to use?
- Every current browser reads it, and it is typically 25–35% smaller than JPEG at the same quality. Older desktop software is the sticking point — convert to PNG or JPG before sending a WebP to someone who will open it in a decade-old application.
