Are my files uploaded to a server?

No. The conversion tools process selected files and pasted text in your browser. Normal network requests still occur to load the website itself.

Are my files stored after processing?

Remold does not store file contents on a server. Temporary workspace data is cleared when you refresh or close the page. Downloaded results remain on your device.

What can I do here?

You can convert, resize and compress images; work with JSON, YAML and XML; use Base64, URL and hash tools; compare text, JSON and code; edit PDF pages; convert CSV, Excel and JSON tables; and format code.

Why are there file limits?

Local processing uses your device’s memory and processor. Limits help prevent freezes or browser crashes, especially on phones. Each tool shows its own limits.

Why was my file rejected?

It may be damaged, its real content may not match its extension, or it may exceed the tool’s size and format limits. Where possible, file type is checked from its first bytes rather than its name alone.

Does it work on mobile devices?

Yes. It works in current versions of Safari, Chrome and similar browsers. Large PDF, spreadsheet and image operations may be slower depending on available phone memory.

Why is an image sometimes larger after conversion?

The selected format and quality can produce a larger file than the source. Re-converting an already compressed small image will not always reduce its size.

Why are PDFs with form fields rejected?

Interactive PDF forms can break during merge or page operations. These files are deliberately rejected to prevent silent data loss.

Does the code formatter run my code?

No. It only changes indentation, spacing and line layout. It does not execute, compile, verify or secure your code.

How do I report a problem?

Use the LinkedIn link in the footer and include the tool, browser, device and a safe example that reproduces the problem. Do not send confidential files or personal data.
