Question 1

Is FileSquash really free?

Accepted Answer

Yes, completely. All 42 tools are free to use with no signup, no watermarks, and no hidden limits. We may introduce optional paid features in the future, but the core tools will always be free.

Question 2

Do you store my files?

Accepted Answer

No. Files uploaded for server-side processing are stored temporarily and automatically deleted within 1 hour. We never access, view, or analyze your files. For many image and PDF tools, processing happens entirely in your browser — your files never leave your device.

Question 3

Is my data safe and private?

Accepted Answer

Yes. All uploads use HTTPS encryption in transit. Server-processed files are stored in isolated temporary storage and deleted automatically. We don't use third-party APIs to process your files — everything runs on our own servers. We use privacy-friendly analytics (Umami) that don't track individual users or use cookies.

Question 4

What's the maximum file size?

Accepted Answer

Most tools support files up to 100 MB. Video tools support files up to 5 GB. The exact limit is shown on each tool's upload area. Client-side tools (image crop, resize, rotate) have no upload limit since processing happens in your browser.

Question 5

Which file formats do you support?

Accepted Answer

Video: MP4, MOV, MKV, WebM, AVI. Audio: MP3, WAV, FLAC, AAC, OGG. Image: JPEG, PNG, WebP, GIF. PDF: Standard PDF files. Each tool shows its supported formats when you visit it.

Question 6

Why is video processing slower than image processing?

Accepted Answer

Image and PDF tools run in your browser using the Canvas API and pdf-lib — they're near-instant. Video and audio files need to be uploaded to our servers where FFmpeg processes them. Processing time depends on file size, the operation, and current server load.

Question 7

Can I use FileSquash for commercial projects?

Accepted Answer

Absolutely. There are no restrictions on how you use the output files. Convert, compress, crop, or watermark files for personal, commercial, or educational use.

Question 8

Do you add watermarks to output files?

Accepted Answer

Never. Your output files are clean — no watermarks, no branding, no metadata injection. What you put in is what you get out (minus whatever processing you asked for).

Question 9

Do I need to create an account?

Accepted Answer

No. FileSquash works without any signup, login, or email. Just visit a tool, upload your file, and download the result.

Question 10

What happens if my file fails to process?

Accepted Answer

You'll see a clear error message explaining what went wrong. Common causes: the file is corrupted, the format isn't supported for that specific tool, or the file exceeds the size limit. Try a different file or format, or contact us if the problem persists.

Question 11

Is there an API?

Accepted Answer

Not yet, but it's on our roadmap. If you need programmatic access to file conversion tools, reach out to us at hello@filesquash.com.

Question 12

How does in-browser processing work?

Accepted Answer

For image and PDF tools, we use your browser's built-in Canvas API and JavaScript libraries (like pdf-lib and ExifReader) to process files directly on your device. Your files never leave your computer, which means instant results and complete privacy.

Question 13

Can I process multiple files at once?

Accepted Answer

Some tools support multiple files — like PDF Merge (combine PDFs), Video Merge (join videos), and Image to PDF (combine images into one PDF). Look for the additional file upload area after adding your first file.

Question 14

Does FileSquash work on mobile?

Accepted Answer

Yes. FileSquash is fully responsive and works on phones and tablets. You can upload files from your device's camera roll or file manager and download results directly.

Question 15

Who built FileSquash?

Accepted Answer

FileSquash is an independent project focused on making file conversion simple, free, and private. We're not backed by an ad network or data broker — we built this because we needed it ourselves.
