About the JPG to PNG
PNG is the go-to when you need lossless storage, transparency support, or a format that survives repeated edits without generational loss. This tool re-wraps your JPG pixels into a clean PNG — note that artifacts already baked into the JPG remain, but no new loss is added.
How it works
The tool unwraps your JPEG's decoded pixels into a lossless PNG container. No new compression artifacts are added — though artifacts already baked into the JPG by its camera or previous save remain, since no converter can undo past JPEG loss.
How to use it
Drop up to 10 .jpg files and press Convert — there are no settings because none are needed. Preview each result, then download files individually or the batch as a ZIP.
Supported formats & limitations
Input: .jpg/.jpeg up to 30MB each, 10 per run. Output: .png, typically larger than the source for photographs (lossless costs bytes). For text-heavy images and screenshots the size gap is smaller and the crispness gain can be worth it.
Common use cases
Converting photos before repeated editing rounds (PNG survives saves without generational loss), feeding image editors that prefer PNG, and preparing images for tools that demand the format. Also the standard fix for 'PNG required' upload fields.
Frequently asked questions
Where are my images processed?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
Can it open JPG, PNG and WebP files?
The common formats are covered — JPG, each up to 30 MB. Queue them one batch at a time.
How many images can I process at once?
Batch runs take up to 10 files at once (30 MB each). There's no account, no daily quota and no watermark — process as many batches as you need.
