Why does a format guide have no upload button?
The directory includes reference pages for common formats. A converter is shown only where this release can produce and validate a real output.

Fast answers for file selection, conversion settings, failed outputs, storage, privacy, and browser compatibility.
Where are my files?
Local conversions remain in browser memory. Results use temporary object URLs and disappear when you clear the job or close the page.
Why did conversion fail?
The file may be malformed, encrypted, use an unsupported codec, or fail output validation. The original remains unchanged.
Can I process a batch?
Yes. Add mixed files, choose an output per row, and retry or download each successful result independently.
What are the local limits?
Images and Office or ebook inputs are limited to 100 MB, decoded images to 80 megapixels, PDFs to 150 MB, media to 500 MB, fonts to 50 MB, and structured text to 25 MB. Archives and 3D or comic packages are limited to 200 MB; archives also allow at most 5,000 entries and 512 MB expanded data. These limits protect browser memory and reject expansion attacks.
How many files can I export?
Allowances are counted separately for each input format per browser and local calendar day. Defaults are 15 for HEIC or HEIF, 20 for AVIF, 10 for archive formats, 50 for structured text, and 25 for other active formats. Every downloaded batch item counts once, and each download button shows that format’s remaining allowance.
