# Photasium > Photasium is a free online photo editor in the browser for everyday crops, captions, colour fixes, and exports. Photos are not uploaded. Editing stays on this device. Photasium is a browser photo editor. After the first load, decode, composite, undo, autosave, and export run on this machine. There is no account, no upload, no paid plan, and no watermark. Official site: https://photasium.com/. Language: English. Open the editor with no sign-in, then create a blank canvas or open an image. You need a network to load the app the first time. After that, editing does not depend on a server. Canvases stay in that browser and do not follow you to another machine. The site does not accept, store, or convert images. An ID photo overlay is a sizing guide, not official approval. Crop, paint, add text, and work with layers in the browser. Free to use, no account, no upload. Photasium is an offline image editor you open in a tab. ## Photo editing tools Jump into the jobs people open a free online photo editor for.

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 posts.** Crop to a square or story, add type, export a JPEG. - **Product shots.** Clean a background mark, tighten the frame, keep the file local. - **Screenshots.** Paint out a name, add a label, download a PNG. - **Print prep.** Resize the image, check the canvas, export at the size you need. ## How to start 1. **Open the editor.** No sign-in. Open the editor, then create a blank canvas or open an image. 2. **Edit the photo.** Use crop, layers, brush, text, and adjustments. Undo and redo as you go. 3. **Export.** Download PNG, JPEG, or WebP. The document is already saved in the browser if you need it again. [Open photo editor](https://photasium.com/editor) ## 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.
