Format conversion

JPG to PNG

Need a lossless intermediate for editing? JPG → PNG is pixel-perfect. Note: details already lost in the JPG will not come back, and PNG files are noticeably larger — that is the format, not the tool.

How to use

  1. Drag your JPG files into the dashed box above, or click to choose files (multi-select and paste are supported).
  2. The tool decodes JPG and encodes PNG locally in your browser, using this page's defaults — no setup needed.
  3. Download results one by one or as a single ZIP; memory is released immediately after processing, with no copies left behind.

FAQ

Will my images be uploaded?

Never. All decoding and encoding for JPG to PNG runs inside your browser via WebAssembly. This site has no image upload endpoint at all, and it works offline.

Is it free? Any limits on file count or size?

Completely free — no sign-up, no watermark. JPG to PNG has no file-count or per-file size limits. Since images are processed on your device, server costs are zero and this can stay free forever.

Will quality drop?

No. PNG is lossless — JPG to PNG preserves every pixel; the trade-off is a usually larger file.

Does it support batch processing?

Yes. Drop dozens or even hundreds of JPG images at once; the memory-budget scheduler processes them locally in a queue. Download individually or as a single ZIP.

Is EXIF metadata or GPS kept in the output?

No, metadata is stripped by default. EXIF and GPS data are removed from the output, so shared files never leak where photos were taken — a privacy feature by itself.

Why did my file get bigger as PNG?

PNG is lossless while JPG is lossy, so PNG keeps every pixel and is naturally larger. If your goal is a smaller file, use JPG compression or convert to WebP instead.
