Common questions
Are my images uploaded to a server?
No. Every conversion in this tool runs entirely in your browser using the Canvas and File APIs. Your images never leave your device, which makes the tool faster, private by default, and safe for confidential or personal photos.
Is there a file size or count limit?
There is no hard limit imposed by us — the tool is bound only by your device's memory. Most modern phones and laptops comfortably process dozens of high-resolution photos at once.
Will I lose quality?
JPG is a lossy format, but at the default 92% quality setting most people cannot tell the difference from the original. Increase the quality slider to 100% for near-lossless output, or lower it for smaller files.
Does it work on iPhone and Android?
Yes. The interface is mobile-first, supports the camera and clipboard, and produces standard files that save directly to your device's downloads or photo library.
Everything worth knowing about the JPG to PNG
Converting JPG to PNG rarely improves an image on its own — the JPG has already thrown away information the PNG has no way to recover. What PNG does give you is a lossless container: from that point forward, every edit, crop, and re-save keeps the pixels exactly as they were. That matters when you're about to run the image through a slide deck, an editor, or a design tool that would otherwise re-compress a JPG on every save and slowly degrade it.
This tool converts any JPG (or several thousand at once) to PNG in your browser. Because the JPG never had an alpha channel, the resulting PNG is fully opaque; if you need transparency, use the Remove Background tool afterwards.
The right reasons to convert JPG to PNG
Stopping generational loss. Every time a JPG is opened, edited, and re-saved it is re-compressed. Ten rounds later, edges are softer and skies are blockier. Converting to PNG once, then editing in PNG, freezes the current quality — subsequent saves lose nothing.
Uploading to systems that demand PNG. Some corporate portals, government forms, and design specs list PNG as the only accepted format. Converting once is faster than arguing with an intake team.
Preparing an image for a design tool. Figma, Sketch, and most illustration apps prefer PNG for imported bitmaps because it plays nicely with their own lossless save behaviour.
The wrong reasons to convert JPG to PNG
'PNG is higher quality.' Not exactly — PNG is lossless from this point forward, but it cannot recover detail the JPG has already discarded. Converting a heavily-compressed JPG to PNG does not un-blur or un-block it.
'PNG will be smaller.' Almost always false for photographs. The resulting PNG will be 3–10× larger than the source JPG.
'I need transparency.' Converting to PNG doesn't magically add an alpha channel. You need a background remover afterwards.
File size expectations
A 2 MB JPG typically becomes an 8–15 MB PNG. If you're converting for archival editing, that's fine — you've got the disk space and you'll benefit from lossless behaviour. If you're converting because you thought PNG was 'better', reconsider: for a photograph you want to publish on the web, JPG or WebP at high quality is almost always the right call.
Bulk conversion
Drop a folder of JPGs and download a single ZIP. Filenames are preserved; only the extension changes. Because PNG encoding is CPU-heavy relative to JPG, large batches (hundreds of files) run noticeably slower than the reverse conversion — a mid-range laptop will chew through them at roughly 3–5 files per second.
- — Editing an image repeatedly? Convert to PNG once, edit in PNG, export to JPG only at the very end.
- — For screenshots that will be shared in a doc, WebP often gives you PNG-quality edges at half the file size.
- — Expecting a smaller file? You want the JPG Compressor or WebP converter instead.
