Image Editor

Brightness, contrast, saturation, filters, text, shapes, draw, watermark and more.

Adjust brightness, contrast, saturation and filters, then add text, shapes, freehand drawing and watermarks — all in one editor that runs in your browser.

What this tool does

The editor covers the everyday adjustments most images need: tonal corrections, colour, filters, and simple annotation. It is not a replacement for professional software, but it handles the great majority of practical tasks without an install or a subscription.

Cleaning up a document scan

This is the editor's most useful non-obvious job. A phone photo of white paper is never actually white — it is light grey, or slightly yellow, or brighter on one side. Raising brightness to lift the paper and then contrast to deepen the ink turns a photo of a page into something that looks scanned.

It also makes the file dramatically smaller. A grey noisy background is expensive for JPEG to encode; flat white is nearly free. A document that would not fit under an upload limit often will after this step alone.

Annotation

Frequently asked questions

Can I undo my changes?

Yes. Adjustments are applied non-destructively as you work, so you can dial them back or reset before exporting. The original file on your disk is never modified — you always download a new copy.

Does it support layers?

No. This is a single-image editor with adjustments and annotations rather than a layered compositing tool. For layer-based work you need desktop software.

How do I make a scanned document look properly scanned?

Raise brightness until the paper reads as white, then raise contrast until the text is solidly black. Stop as soon as faint marks start to vanish. The phone scanning guide covers the full workflow.

What format should I save in?

JPG for photographs and document scans destined for upload. PNG if the image contains text or graphics, or if you need transparency.

Can I edit several images at once?

The editor works on one image at a time. For batch operations, use the dedicated tools — Watermark, Rotate, Resize and Compress all handle multiple files.

Are my images uploaded?

No. All editing happens on a canvas in your browser. Nothing is transmitted and nothing is stored — closing the tab discards everything.
