Common questions

Transparent, no fluff — quick answers.

Are these tools free? ⌄

Yes — every tool on this site is free to use. If you’d like to support the project, tap ☕ Support.

Do you store my files or inputs? ⌄

Many tools are designed to be “quick and disposable.” Some tools process files on the server to produce an output (like a PDF), but the goal is always minimal retention.

What file types do the tools support? ⌄

Each tool lists supported file types right on its page (for example: .html → .pdf, .vtt shifting, .srt/.scc/.itt → .vtt, JPG/PNG cropping). If your file isn’t supported yet, request it below.

Is there a file size limit? ⌄

Some tools have practical limits depending on how the conversion works (browser memory or server processing). If you hit an error on a large file, send the tool name + rough file size via Contact and I’ll tune the limits.

What’s the best way to report a bug or wrong output? ⌄

Use the Contact page and share: the tool name, what you uploaded, what you expected, and what you got. Screenshots help a lot.

Can I request a new tool? ⌄

Yes — use the form in the next section. Even a one-liner helps.
