About this editor
The Image Editor is a browser-based bitmap tool for drawing from scratch and making straightforward changes to an image from your device.
Imported images keep their decoded pixel dimensions.
Drawing and editing features
Tools for common drawing and image-editing tasks.
Crop and resize
Crop to a rectangular area or scale the current image content to new dimensions, with an optional aspect-ratio lock.
Text and basic shapes
Add single-line bitmap text and draw lines, outlined rectangles and outlined ellipses using the selected color and brush size.
Select and move pixels
Select a rectangular bitmap region and move its pixels to another position within the canvas.
Undo and redo
Step backward or forward through recent edits. The history is limited by the browser memory available.
Import and export
Open images from your device and download the edited bitmap as PNG, JPG or WebP.

Supported image formats
Import
Open local PNG, JPEG/JPG and WebP images. The decoded image must remain within the displayed file, dimension and pixel limits.
PNG export
PNG preserves transparent areas and is suitable when lossless bitmap output or transparency is important.
JPG export
JPG does not support transparency. Transparent areas are placed on a solid white background during export.
WebP export
WebP can preserve transparency where the browser supports WebP canvas export. Unsupported or failed WebP output is not downloaded under a misleading extension.
How it works
- Start with the blank canvas or open a supported image stored on your device.
- Choose a drawing or editing tool. Adjust the shared color, brush size or contextual text controls where relevant.
- Draw, erase, fill, add text or shapes, or select and move a rectangular pixel region.
- Crop the image or resize its current content when different canvas dimensions are needed.
- Use undo and redo for recent changes, or clear the canvas when you want to start again.
- Choose PNG, JPG or WebP and download the edited image to your device.
Practical uses
The editor is intended for quick bitmap work that does not require installing specialist software.
- Annotate a screenshot with freehand marks, text or simple shapes.
- Crop an image to the relevant area or resize it to specific pixel dimensions.
- Create a quick sketch or simple diagram on a blank canvas.
- Add a short label or caption directly to an image.
- Clean up small areas with the eraser, fill bucket or pixel selection tool.
- Prepare a simple graphic and export it in a common browser-supported bitmap format.
Important limitations
- Imported files are limited to 10 MiB, 8192 pixels per side and 12 MP decoded pixels.
- It is not a layered or vector editor. Applied text, shapes and moved selections become normal bitmap pixels.
- Text is single-line and cannot be edited as text after it has been applied.
- Pixel selection is rectangular and can be moved, but not rotated or scaled.
- SVG and PDF export are not available.
- WebP export depends on native support in the current browser.
Frequently asked questions
Is my image uploaded?
No. The image is read and edited in your browser, is not uploaded to our server and is not stored by fourwww.
Which image formats can I open?
You can open local PNG, JPEG/JPG and WebP images that remain within the configured file, dimension and decoded-pixel limits.
Which formats can I save?
The editor exports PNG, JPG and WebP using your browser's native canvas support.
Does JPG preserve transparency?
No. JPEG has no transparency support, so transparent areas are exported on a white background.
Can I crop and resize an image?
Yes. Crop keeps a selected rectangular region, while resize scales the current bitmap content to the chosen dimensions. Aspect-ratio locking is available.
Can I add text?
Yes. You can place movable single-line text, choose a system font, size, bold setting and color, then apply it to the bitmap.
Can I move something after drawing it?
The rectangular selection tool can cut and move a selected pixel region. It does not identify or retain individual text, shape or drawing objects.
Does the editor work on mobile devices and tablets?
The interface supports responsive layouts and pointer or touch input. Practical editing comfort and export support depend on the device, browser and image size.
Do I need an account?
No. The editor can be used without registration or an account.
Is this a vector or layered editor?
No. It is a bitmap editor with a single canvas. It does not provide vector objects, layers or permanently editable elements.
