What actually changes when you convert
JPG and PNG solve different problems. JPG throws away detail your eye is unlikely to miss and stores photographs in remarkably little space. PNG keeps every pixel exactly as given and supports transparency, at the cost of much larger files for photographic content.
Converting JPG to PNG stops any further loss from that point on, but it does not undo the loss already baked in. The JPEG artefacts in your source — the faint haloes around hard edges, the blocky patches in flat sky — are pixels now, and PNG will preserve them perfectly. Converting will never make an image look better than the JPG you started with; it stops it getting worse.
When PNG is the right choice
Reach for PNG when pixel fidelity matters more than file size, or when something downstream demands it. Those cases are narrower than people assume, which is why so many websites are slower than they need to be.
- Logos, icons and diagrams — flat colour and hard edges, exactly what JPG handles worst.
- Screenshots, especially of text, where JPG's ringing artefacts make small type look dirty.
- Images you will edit repeatedly: each JPG re-save loses a little more, PNG loses nothing.
- Anything needing transparency, which JPG cannot represent at all.
- Printers, publishers and design tools that specify PNG or reject lossy formats outright.
Transparency: the thing this cannot give you
This is by far the most common disappointment, so it is worth being blunt. JPG has no alpha channel. There is no transparency information anywhere in your file to recover, and no converter can invent it. A JPG with a white background becomes a PNG with a white background.
If you need a transparent logo, either go back to the original vector or layered file, or remove the background as a separate editing step. Conversion alone will never do it.
Why the PNG comes out larger
Expect a photograph to grow by roughly three to five times. That is not a fault: JPG achieved its size by discarding data, and PNG's lossless compression cannot match that on the noisy, continuously-varying pixels a photograph is made of.
Graphics behave differently. A logo of a few flat colours often converts to a PNG *smaller* than the JPG, because PNG compresses runs of identical pixels extremely well — and it looks better too, since the JPG was fighting its own worst case. If a converted photograph is too large for the web, WEBP is usually the better answer: smaller than both, and supported by every current browser.
Converting without uploading your photos
Every step runs inside your browser, using the WebAssembly and Canvas APIs your device already ships with. No file is uploaded, no copy is kept, and nothing sits in a queue on a server waiting to be deleted — which is also why the tool keeps working with the network disconnected.
That also means batches are quick, since nothing is waiting on an upload and a download. Twenty images convert in the time it takes to send one to a server, and the EXIF metadata in your photos — camera model, timestamps and, on phone photos, GPS coordinates of where you took them — never reaches anyone else's machine.
Frequently Asked Questions
Why convert JPG to PNG?
PNG is lossless, so it's the right choice when you need to edit an image repeatedly, take screenshots of it, or require exact pixels. Note that PNG files are usually larger than JPG.
Will the PNG have transparency?
JPG has no transparency, so the converted PNG keeps the same solid background.
Is there a file limit?
You can convert up to 20 images at once, up to 50 MB each.
Does converting JPG to PNG improve the quality?
No, and this is worth understanding. PNG preserves exactly what it is given, including the compression artefacts already present in the JPG. It prevents further loss from now on; it cannot recover detail the JPEG encoder discarded.
Can I get a transparent background this way?
No. JPG has no alpha channel, so there is no transparency data in your file to recover. Go back to the original vector or layered file, or remove the background as a separate step.
Why is my PNG so much bigger than the JPG?
Because JPG got small by throwing detail away and PNG keeps everything. Photographs typically grow three to five times. Graphics with flat colour often shrink instead, since that is where PNG's compression is strongest.
Should I use PNG or WEBP for my website?
WEBP, in almost all cases. It is lossless when you need it to be, supports transparency, and produces files 25-35% smaller than PNG. Every browser in current use supports it. PNG remains the right answer when a tool or client explicitly requires it.
Can I convert several JPGs at once?
Yes — up to 20 files per batch, downloadable individually or as a single ZIP. Since conversion runs locally, a batch is as fast as the files can be read from disk.
Is the EXIF data kept?
Standard PNG does not carry EXIF the way JPG does, so camera settings, timestamps and GPS coordinates are dropped in conversion. That is a privacy gain if you are publishing the image and a loss if you were relying on the metadata — export it first if you need it.
