About ImageForge
ImageForge is a free image editor that runs entirely in your browser. No uploads, no account, no sign-up — open the page and start editing.
Why it exists
Most "free online image editor" sites quietly upload your picture to a server, process it there, and hand it back. That is slow, it breaks on large files, and it means your photo — which might be a contract, a medical scan or a family picture — sits on someone else's machine.
ImageForge takes the other route: every operation happens on your own device using the HTML5 Canvas API. The page you load is the whole application.
What it can do
- Layers — create, reorder, merge, blend, adjust opacity
- Selection — rectangle, ellipse, lasso, magic wand, colour range
- Adjustments — brightness, contrast, saturation, hue, levels, curves
- Filters — blur, sharpen, edge detect, emboss, noise, vignette, and more
- Brushes and shapes — pencil, line, rectangle, ellipse, text, gradient, fill
- Transforms — crop, resize, rotate, flip, perspective
- Formats — PNG, JPEG, WebP, GIF, BMP, and SVG for vector output
- Transparency — full alpha channel support, with a checkerboard backdrop
Who it is for
- Developers who need to crop a screenshot or mock up an icon without opening heavyweight software
- Writers and teachers preparing images for articles or slides
- Anyone on a locked-down or shared machine where installing software is not an option
- Anyone who would rather a private image never touched a server
What it is not
It is not a replacement for Photoshop or GIMP on large, multi-hundred-megabyte files. Browser memory is the practical ceiling. For a quick edit it is faster than installing anything; for a 400-layer print project, use a desktop application.
Technology
- Plain JavaScript and the HTML5
<canvas>API — no framework - Webpack for bundling
- Served as static files from Cloudflare Pages, so there is no backend to attack or to go down
- Upstream: built on miniPaint (MIT)
