A browser application can look ready long before you know whether it will work for your files. The canvas loads, the panels look familiar, and the temptation is to import an important project immediately. A better first test follows the file all the way from an untouched source to a result you can reopen.
Craft Apps is a useful setting for that discussion. Its public collection offers 13 browser-based tool entries, and its PhotoCraft page explains both the intended image workflow and several limits of the current web build. This article draws on those pages and an inspection of the loaded editor. No edit-and-export round trip was completed, so the checklist below is a proposed test, rather than a compatibility result.

Define an observable result before importing a file
Choose one task whose outcome can be checked outside the editor. For example, a small image with a readable title at its intended display size gives you a concrete question. “Try all the features” does not. Record the source dimensions and keep the original separate from the experiment.
The photocraft landing page discusses layered image editing, text and composition, and a PSD-oriented workflow. It also cautions that a PSD can contain features that do not translate perfectly. A reasonable test therefore starts with a modest file and a known expectation. The extension alone does not tell you whether a particular layer effect will survive a round trip.
If your task depends on editable text, check editable text. If it depends on transparency, check transparency. An attractive preview can hide a loss that only becomes obvious when somebody tries to use the file later.

Separate the landing-page examples from the running build
Documentation screenshots are useful for explaining an interface. They are weaker evidence for what a particular hosted version can do. PhotoCraft’s product page explicitly identifies its images as upstream examples and says that the browser integration may expose different controls and output options.
In the actual hosted editor, the opening workspace loaded with New document and Open controls. Opening the new-document dialog showed dimensions, resolution, RGB color mode, bit depth and background settings. That observation establishes that the controls were visible. It does not establish successful import, rendering fidelity or export behavior.

This separation is useful when reporting a bug, too. Name the current build and the exact file behavior you observed. A screenshot from a different release can help explain your expectation, but the report should still identify what happened in your session.
Treat saving as a separate acceptance step
The live product page says the web build opens files through the browser picker and saves by download. It also states that there is no web autosave or crash recovery. Those details change how you should structure a first test: keep it short enough to save and inspect before investing substantial work.
After using an available save or export command, locate the downloaded file. Reopen it in the application that will receive the work, or in a fresh editing session when continued editing is the requirement. Check the dimensions and the properties that mattered in your original task.
Keep a working version separate from a sharing copy when the available formats support that distinction. A flattened image and a reusable layered project serve different purposes. A file that opens successfully can still be unsuitable for the next step, so acceptance should follow the intended use.
Write down what passed and what remains unknown
A small test record can be a few lines: the source file, the intended change, the save option selected, the location of the download and the result of reopening it. Add any mismatch you saw. This makes the next decision easier than relying on whether the canvas looked convincing.
For this inspection, the public product notes, loaded workspace and new-document controls were observed. Import fidelity, export fidelity and recovery behavior were not independently tested. The site’s stated limits remain part of the decision.
A browser photo editor becomes useful for a particular job when its file workflow supports that job. Start with a source you can afford to experiment on, define a visible result, and finish the saving check before scaling up the work.
