About the JPG to PNG
This converter decodes your JPG with Imagick and re-encodes the pixels as PNG, a lossless format. The important word is re-encodes: the pixel data is copied faithfully, but it is copied from a JPG that was already compressed, so every artefact the original camera or export baked in comes along for the ride, permanently.
The genuine reason to do this is to stop the bleeding. Once an image is PNG, editing and re-saving it repeatedly will not degrade it further the way each JPG save quietly does — so it is a sensible step before a round of edits, or when a tool or platform demands PNG. Going the other way, PNG to JPG shrinks files back down, and image to WebP is smaller than both for the web.
Set expectations honestly: converting JPG to PNG does not improve the image. It cannot recover detail JPG discarded, nor add transparency — a JPG has no transparent pixels, so the PNG comes out fully opaque. It will usually make the file considerably larger, since lossless compression handles photographic noise far less efficiently than JPG does. Metadata is stripped. Convert one image or up to 30, a batch returning a ZIP. Files are uploaded, processed under random names in a non-public folder, and deleted when the request ends; 20 MB each, 25 MB total.
Frequently asked questions
Does converting to PNG improve quality?
No. It preserves exactly what the JPG already contains, artefacts included. Nothing is recovered — the benefit is that no further loss happens from here on.
Why is the PNG so much bigger?
PNG compresses losslessly, which works well for flat colour and badly for photographic noise. A photo PNG several times the size of its JPG is completely normal.
Will my image get a transparent background?
No. JPG cannot store transparency, so there is none to carry over. The PNG is opaque — making a background transparent is an editing job, not a conversion.
Is metadata kept?
No. EXIF and other metadata are stripped from the output images.
Can I convert a batch?
Yes — up to 30 images, each under 20 MB and 25 MB in total. One image downloads directly; several come back as a ZIP.
