PNG · JPG · WEBP
Image converter
Drop an image and choose the output: PNG, JPG or WEBP. Your browser's own decoder and encoder do the work, so the picture is read from disk and written back to disk without a network request in between.
Choosing JPG flattens transparency onto the background colour; PNG output stores every pixel exactly, alpha included. No metadata from the original file is carried over.
How to convert an image
Add the image
Drop a PNG, JPG, WEBP, GIF, BMP or AVIF file on the box, paste it from the clipboard, or pick it from your disk.
Choose the output and settings
Pick PNG when transparency has to survive, JPG when the picture is a photograph, or WEBP for a small asset on the web. Quality applies to JPG and WEBP alone, since PNG is lossless.
Download the converted file
The result reports its pixel dimensions and its new weight. Save it, then run another image through the same page without reloading.
How the three output formats differ
A browser decodes almost anything — PNG, JPG, WEBP, GIF, BMP, AVIF — into the same pixels and then re-encodes them into the format you ask for, which is why one page can serve all of them. PNG and WEBP carry an alpha channel; JPG has none. PNG is lossless, while JPG and WEBP take a quality setting and discard detail to save bytes.
The trip through the canvas adds nothing and restores nothing: a GIF contributes only its first frame, a JPG contributes the artefacts its encoder already left behind, and metadata such as EXIF is not copied into the new file. Dimensions are preserved unless you set a maximum width or height, which only ever scales down. For photographs, JPG or WEBP will always beat PNG on size; for screenshots and flat graphics, PNG keeps edges and transparent areas exact.
Image converter questions
Does my picture get uploaded to a server?
No. Decoding and encoding use image APIs that already ship with your browser, so the bytes are read from your disk and written back to your disk. After the first load the page needs no connection at all.
Which format should I pick for a photograph?
JPG or WEBP: both spend a little sharpness to buy a much smaller file, and both are read by everything that matters. WEBP is the more efficient of the two; JPG is the safer choice for print shops, older editors and email attachments.
What does the quality setting change?
It changes the JPG and WEBP outputs only, because PNG is lossless and takes no quality argument. 92 is a sensible starting point for photographs; push it towards 100 for graphics with sharp edges or text, where compression shows up as ringing.
Is there a limit on file size or count?
64 MB per file. Each image is converted on its own and comes back as its own download rather than a bundle, so a bigger picture is best resized in an editor before it reaches the browser.
