Aseprite Online: How to Open and Edit an Existing Sprite in Your Browser

If you already have an .aseprite file, the useful question is whether a browser tool can open its layers and animation, let you make the change you need, and save a useful result. A drawing website that exports a PNG may be perfectly good for new artwork, yet unsuitable for continuing an existing layered project.

Aseprite's official downloads are desktop applications for Windows, macOS, and Linux. The browser tools below are separate products. Pick one according to the file you have and the format you need afterward; an Aseprite import button does not establish complete compatibility. Aseprite FAQ

Start with the file, then choose the tool

For a quick check, use the Xprite Aseprite file viewer. It opens local .ase and .aseprite files, previews frames and animation tags, and exports a PNG frame or a GIF animation. Its Edit button carries the original file into the editor. Preview-only layer visibility changes do not carry across. Xprite user guide

This is useful when someone sends you a project and you first need to inspect its contents. If you only need an image for a message or an animation preview, the viewer may finish the job. If the task requires drawing or changing the document, open the editor.

The distinction between opening a project and exporting an image matters throughout this comparison. PNG and GIF are delivery formats: they can show the finished artwork without preserving an editable layer structure. A tool's own project format can preserve more of its working state, but that does not necessarily produce an Aseprite document for your collaborator.

Tool	Browser option	Existing Aseprite file	What to check before committing
Xprite	Browser editor and separate viewer	Opens `.ase` / `.aseprite`; editor can save Aseprite files	Inspect the imported project; unsupported features and browser resource limits can prevent opening
Novaboard	Free browser editor	Developer documents `.ase` / `.aseprite` import	Confirm your required output; documented GIF, MP4, sheet, and atlas export does not establish Aseprite write-back
Manabit	Browser editor; paid license also covers Windows	Documents layers, frames, and tags becoming layer animations	Saving requires sign-in; documented output includes images, GIF, and animation strips
Pixelorama	Free web version alongside desktop apps	Documents Aseprite import; v1.2.2 added Aseprite export	Check import limitations and the output; `.pxo` remains its own project format
Aseprite	Official desktop downloads	Native format and workflow	Requires a desktop installation

When each browser option makes sense

Choose Xprite when the immediate task is inspecting an Aseprite file or making a browser edit while keeping an Aseprite file as the intended output. It has a dedicated viewing route; Edit opens the original file in the editor. Use File → Save As → File Manager to save a separate result on your device, then reopen it in the application that will use it next. The save extension is not a guarantee that every feature survives.

Consider Novaboard when you want a free browser animation workspace and image or game-asset output. Its developer lists timeline tags, onion skinning, indexed color, and non-destructive layer effects. Those are reasons to investigate it for drawing and animation. For an existing project, check the imported structure and confirm its save options before promising an .aseprite file back to someone. Novaboard developer page

Consider Manabit when sprites and map building belong in the same project. Its Aseprite import maps the incoming content into its own animation system. That is a workflow conversion to evaluate, especially if your existing tags have specific meaning. Its free documentation lists one local project and one cloud project with 25 MB of storage; saving requires an account, and the pages also warn that some browser features may require a license.

Consider Pixelorama when you want a free editor with both Aseprite import and export. Version 1.2.2 added Aseprite export on September 9, 2026; the official browser app inspected for this article identified itself as v1.2.3. Its import checklist includes tilemap layers and linked cels, but excludes slices, color profiles, external files, masks, and cel extra data. Grayscale converts to RGBA. Export availability does not restore information omitted during import, so check a representative file before switching. Pixelorama v1.2.2 release, Pixelorama import, official browser build

Keep desktop Aseprite for workflows that depend on it

If your work relies on a specific Aseprite extension, script, command-line export, or exact native document behavior, keep that workflow in Aseprite until you have checked the alternative against a representative copy. Its official documentation covers scripting, extensions, and tilemaps; a browser tool offering similarly named features does not make those workflows interchangeable. Aseprite documentation

For a browser edit, keep the original, inspect layers and timing after import, and save a separate result. Choose the output according to the next step: an editable project for more work, a sheet for a game pipeline, or a PNG/GIF for viewing. That small check is more useful than choosing by a compatibility slogan.

Open your file in the viewer or start editing in Xprite.
