JPG is great for photos and terrible for anything with sharp edges or transparency. Filemorph turns a JPG into a lossless PNG on your iPhone in a tap — no upload, no account, works in Airplane Mode.

Screenshots that were saved as JPG, logos pulled from an email, a signature you photographed — sooner or later a website or app demands PNG. PNG is lossless and supports transparency, so it is the format editors, print shops and upload forms ask for when edges matter. Converting on your phone means the file is ready before you get to a computer.
Filemorph decodes the JPG with Apple's ImageIO framework and re-encodes it as PNG. Nothing is upscaled or "enhanced" unless you ask: the pixels are preserved exactly, and any JPG artifacts that were already there stay there — PNG stops further loss, it cannot undo old compression. You can convert one image or a batch of three at once on the free tier.
In the app: Convert → To PNG.
PNG is lossless and supports transparency. Use it for screenshots, UI assets, logos, diagrams and anything you will edit again; keep JPG for photos where file size matters more. Converting to PNG also sidesteps upload forms that reject JPG.
Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This conversion is in the free tier.
Yes. JPG to PNG is in Filemorph's free tier, including a batch of up to 3 images at once.
Usually, yes — often 3 to 10 times larger. PNG stores every pixel with no lossy compression, so use it when quality or transparency matters, not to save space.
No. Converting to PNG stops further loss from that point on, but it cannot restore detail a JPG already lost. If you need to repair a low-quality JPG, try Filemorph's AI Enhance (Pro).
