Are my images uploaded for conversion?

No. Conversion uses the canvas encoder built into your browser and runs entirely on your device — there is no server involved at any step.

Is converting JPG to PNG lossless?

The conversion itself does not lose anything — PNG stores exactly the decoded pixels. But it cannot recover detail the JPG compression already discarded, and the PNG file will usually be much larger than the JPG was.

What happens to transparency when converting to JPG?

JPG has no alpha channel, so transparent areas are composited onto a white background. If you need to keep transparency, convert to PNG or WebP instead.

Should I use WebP instead of JPG?

For the web, usually yes: WebP is 25–35% smaller at the same visual quality and supports transparency. Stick with JPG when the recipient might use older software, or when a platform explicitly requires JPG uploads.

Does the converted file keep EXIF metadata?

No. Re-encoding through canvas produces a clean file without EXIF, GPS coordinates or camera information — the same privacy benefit as the other tools in this cluster.

Image Format Converter

Convert between PNG, JPG and WebP in your browser — batch, instant, and nothing gets uploaded.

JPG, PNG and WebP — you can also paste a screenshot with Ctrl+V / Cmd+V

Processed locally, never uploaded

100% private — your images never leave your device

Everything on this page runs locally in your browser with JavaScript. No image is ever uploaded to a server, so you can safely process ID photos, screenshots with personal data, or any confidential picture.

How the converter works

Add images in any mix

Drop PNG, JPG and WebP files together — each is converted independently. Paste screenshots directly with Ctrl+V / Cmd+V.

Choose the output format

Pick PNG for lossless quality and transparency, JPG for maximum compatibility, or WebP for the best size/quality ratio on the modern web. Adjust quality for JPG and WebP.

Download converted files

Grab files one by one or as a ZIP. Conversion goes through canvas re-encoding, so EXIF metadata never makes it into the output.

PNG vs. JPG vs. WebP — when to use which

PNG is lossless and supports transparency, which makes it right for logos, UI screenshots and graphics with sharp edges — but wrong for photos, where it produces huge files. JPG is the universal photo format: small, compatible with everything, no transparency. WebP typically beats JPG by 25–35% at the same visual quality and supports transparency too; its only cost is that a few older apps still cannot open it.

A practical rule: send JPG when compatibility matters (email, forms, older software), use WebP for your own websites, and keep PNG for graphics and screenshots that must stay pixel-perfect. Whatever direction you convert, this tool re-encodes through canvas locally, so the output starts clean — no EXIF, no GPS, no camera fingerprint.
