Convert one or many JPG images to PNG. PNG is lossless, so the converted file will not degrade on further editing or re-saving.
Last updated 27 August 2026
Drag & drop files here, or
Up to 30 files, 25 MB each
Select one or more .jpg or .jpeg images.
Each image is decoded and re-encoded as PNG in your browser.
Save the PNGs individually or as a ZIP.
The JPG is drawn to a canvas at full resolution and exported with toBlob("image/png"). Every pixel currently in the JPG is preserved exactly in the PNG.
Convert to PNG when you need to edit an image repeatedly without accumulating JPG compression artefacts, when a tool or platform specifically requires PNG, or when you are about to add transparency in an editor.
Note that the JPG has already discarded some detail — converting to PNG locks in the current quality but cannot restore what the JPG compression removed. The PNG will also usually be larger.
No — it will look identical. PNG preserves exactly what is in the JPG; it does not undo compression that already happened. The benefit is no further loss from here on.
PNG is lossless, so it stores full colour information for every pixel. Photos, which have millions of subtly different colours, do not compress well as PNG.
Yes, up to 30 per batch, with a ZIP download.
No. Conversion is done entirely by your browser.
