The JPG Editor is a free in-browser tool for retouching JPG photos — the everyday format from phone cameras and the web. It is tuned for photographic edits: cropping, straightening, exposure-style filters, and adding text or shapes to a photo before you share it. Because JPG has no transparency channel, the editor always keeps a solid background rather than a checkerboard.
Will editing and re-saving a JPG reduce its quality?
+
JPG is a lossy format, so every save re-runs DCT compression and discards a little detail — this is "generation loss." The editor minimizes it by re-encoding only once, at a high quality factor, when you export. For repeated round-trips, keep an original copy; for a single edit-and-share the difference is invisible. The tool is free with no quality cap on the editing itself.
Can I control the JPG quality and file size when I export?
+
Yes. When you download, the JPG is written at a high quality factor that balances sharpness against file size, and EXIF orientation is baked in so the photo is never sideways. You can crop to shrink dimensions, which is the most reliable way to reduce a JPG's size without visible artifacts. There is no alpha channel, so any erased area fills with the background color rather than turning transparent.
Are my JPG photos uploaded anywhere while I edit?
+
No. Edits happen locally in your browser canvas, so your JPG — and any location or camera EXIF metadata it carries — never leaves your device unless you explicitly save. Exporting writes a fresh JPG that drops most embedded metadata, which is a handy privacy side effect before posting a photo publicly.
