Make a lossless PNG copy of any JPG — the right base for editing, annotation, and tools that require PNG input. Everything runs on your device.
How it works
Convert a whole batch to PNG without sending anything to a server.
01
Pick a file or drag it straight in — drop in .jpg or .jpeg photos.
02
Slide between smaller and sharper. 80 is a great default for most photos.
03
It saves straight to your device the moment it’s ready — no upload, no waiting.
Why PNG
Learn
Every time a JPG is edited and re-saved as JPG, it is compressed again, and the artifacts compound — the digital equivalent of photocopying a photocopy. Converting to PNG first freezes the image losslessly: you can crop, annotate, and re-save the PNG as many times as you like without any further decay.
That makes JPG to PNG the right first step before heavy editing, annotation rounds, or any workflow where the file will be opened and saved repeatedly.
Be clear about the direction of this conversion: PNG faithfully preserves the pixels your JPG has right now. It cannot resurrect detail that JPG compression already discarded — no format conversion can. If the JPG shows blocky artifacts, the PNG will show the same artifacts, just without adding new ones.
Plenty of systems insist on PNG: app-store screenshot uploads, some CMS asset pipelines, documentation platforms, icon and asset workflows in design tools. Converting a JPG here produces a standards-perfect PNG accepted by all of them — generated locally, so even confidential screenshots stay on your machine.
FAQ
PNG is lossless, so edits and re-saves stop degrading the image. Many tools, forms, and workflows also simply require PNG input.
No — it faithfully preserves the pixels the JPG already has. It prevents FUTURE quality loss from repeated saving, but cannot restore detail the JPG compression removed.
Usually yes, often several times larger. That is expected: PNG stores every pixel exactly instead of compressing it lossily.
Never. The conversion is 100% local to your browser — ideal for private photos and confidential screenshots.
PNG stores pixels losslessly; JPG compresses them aggressively. For photographs, 3–10× larger is normal. The size buys you immunity from further quality loss.
No — JPGs have no transparency to preserve. The PNG will be fully opaque; you can add transparency later in an editor.
