PNG, JPEG, and WebP. These cover the vast majority of images people need to edit. Formats like TIFF or HEIC require the full editor.
There's no server-side limit because files never leave your device. In practice, very large images (over 50 MB or 10,000+ pixels) may be slow depending on your device.
Use the full PaintDim editor — it supports layers, filters, selections, text, and more. Also free, no signup.
