Input → browser decoding or packaging → new downloadable output
Keep the original file until you have checked the downloaded result. Processing limits depend on browser memory and image dimensions.

The upload control lists the supported inputs. Formats must also be decodable by your browser. SVG and camera RAW files are not accepted here.

| JPG / PNG / WebP | Supported where listed |
| GIF | Not intended for animation; animated frames are not preserved |
| HEIC / RAW / TIFF | Not supported by this page |
Tips for better results
- Try one smaller image first on a phone.
- Compare the downloaded result at full size before replacing an original.
- Use PNG when transparency matters; use JPG or WebP when a smaller photographic file matters more.
FAQ
Does Adjust Image Brightness upload my photos?
No. Processing runs in your current browser tab, and the selected files are not sent to Callimage.
Which image formats can I use?
This page accepts the formats listed in its upload area. Actual decoding and encoding support can vary slightly by browser.
Will the downloaded file match the original quality?
A newly encoded image can differ in file size and, for lossy formats, pixel detail. Use a high quality setting when available.
Why can a very large image fail?
Browsers limit canvas dimensions and memory. This tool stops unusually large jobs before they can freeze a phone or low-memory computer.
Can I use the result for print work?
Yes for ordinary layouts, but browser processing does not guarantee preservation of ICC profiles or press-level color management.
