Photo Editor
Photo Editor applies brightness, contrast and colour adjustments live on a canvas, with preset filters and simple drawing tools. It is a quick correction pass for exposure and colour cast rather than a replacement for a full desktop editor.
How to use Photo Editor
- Upload the photograph.
- Adjust brightness, contrast and colour sliders, or pick a preset filter.
- Apply the edit and download the corrected image.
Where Photo Editor is useful
- Brightening a photo taken in poor light.
- Correcting a colour cast from indoor lighting.
- Adding simple annotations or a hand-drawn highlight to a screenshot.
Formats, algorithms and limits
Adjustments are applied as pixel operations through the canvas 2D context — brightness, contrast and colour shifts are linear transforms on each channel. The image is re-encoded once after editing, so saving in PNG keeps the result lossless while JPEG re-applies compression.
Troubleshooting and honest limits
- Correct exposure before contrast: brightness changes reveal clipping more clearly.
- Small adjustments look natural; combine several strong ones and the image starts to look processed.
- Export to PNG if you plan further editing, and to JPEG only for the final delivery copy.
Frequently asked questions
Are these edits destructive?
Only to the exported copy: the original file is untouched. Within the editor, adjustments apply live so you can keep tweaking before saving.
Can I crop or resize here too?
The dedicated Cropper and Resizer tools handle geometry, including exact pixel dimensions; this tool focuses on tone, colour and drawing.
Is there an undo?
Adjustments are slider-based and re-applied from the loaded image, so you can return a value to its default to undo that change.
Which formats can I export?
The standard browser formats — PNG for a lossless result, JPEG for a smaller file, and WebP where you want good compression in a modern container.
