Use Cases
These pages walk one real job end to end: compressing a photo to a 100 KB email limit, converting an iPhone HEIC to JPG, merging a PDF online for free, turning JSON into an Excel-ready CSV, splitting a PDF into single pages, and stripping metadata from an image before sharing. Each is solved with an in-browser tool — no upload, no account.

Frequently asked questions
Are the walkthroughs tied to this site's tools?
They use this site's tools for the steps, but the trade-offs are general — when re-encoding costs quality, what a desktop tool does better at scale, what the browser's memory ceiling means for a batch. If you use different software, the reasoning still transfers.
Do the steps work on a phone?
Yes. The tool surfaces are sized for touch targets and the layouts collapse to one column; the practical limits are the browser's own — roughly 100 MB per file and 250 MB per batch, with several image tools applying lower, documented ceilings because decoded pixels dwarf the file size.
Is any of this uploaded?
No. Every step runs in the browser tab: the site has no file-processing API routes, and the Content-Security-Policy's connect-src 'self' blocks the page from sending your bytes anywhere. Open DevTools → Network while a tool works and watch the payload column stay empty.
Ready for the tool itself?
Each walkthrough links the tool it uses; the category hubs list every tool on the site, grouped by the kind of file you are working on.
