Photasium is a free online photo editor that runs in the browser as an offline image editor.

Does Photasium upload images?

No. Editing, autosave, and export run on this machine.

Does it work without a network?

You need a network to load the app the first time. After that, editing does not depend on a server.

Yes. There is no paid plan and no watermark on export.

Do I need an account?

No. There is no account and no sign-in.

Is it a Photoshop alternative?

For crop, layers, type, paint, and export, yes — a lighter one. It is not a clone of Photoshop.

What tools are included?

Layers, brush, eraser, fill, crop, text, adjustments, and PNG, JPEG, or WebP export.

What files can I open?

PNG, JPEG, WebP, and GIF, or a blank canvas.

A full editor, not a one-click filter

Photasium is a free online photo editor with a real canvas: a toolbar, layer stack, and document you can come back to. Open a photo or start blank. Move layers, crop the working area, paint, add type, then export.

It is also an offline image editor. After the app loads, compositing and saves run on this machine. There is no account and no project sitting on someone else’s server.

What you can do

Photo editing

Crop, resize, flip, rotate, and retouch with brush, eraser, and fill. Adjust brightness, contrast, and saturation on a raster layer.

Text and layout

Add text layers, set size, weight, align, and stroke, then transform them on the canvas next to the photo.

Layered documents

Keep rasters, type, and groups in one file. Duplicate, lock, and reorder instead of flattening after every change.

Local export

Download PNG, JPEG, or WebP when you are done. Autosave writes the canvas into this browser so you can reopen it.

Built for everyday edits

Use a free online photo editor when the job is a crop, a caption, a colour fix, or a clean export — not a subscription and a 4GB install.

Social postsCrop to a square or story, add type, export a JPEG.
Product shotsClean a background mark, tighten the frame, keep the file local.
ScreenshotsPaint out a name, add a label, download a PNG.
Print prepResize the image, check the canvas, export at the size you need.

How to start

Open the editor
No sign-in. Open the editor, then create a blank canvas or open an image.
Edit the photo
Use crop, layers, brush, text, and adjustments. Undo and redo as you go.
Export
Download PNG, JPEG, or WebP. The document is already saved in the browser if you need it again.

Offline, in the browser

A lot of “online photo editors” send the file to a backend. Photasium does not. Decode, composite, undo, and export run in the client. Autosave uses on-device storage.

Load the app once. After that, you are not waiting on an image API. That is the difference between a web UI on a server and a free online photo editor that is actually in-browser only.
