Frequently Asked Questions
Clear answers about privacy, limits, formats and how SonoFiles works.
Is SonoFiles free to use?
Yes. The current SonoFiles tools are free to use with no account, watermark, daily quota or paid size unlock. Technical safety limits are shown clearly inside each tool.
Are my files uploaded or stored?
Current live tools are designed to process files locally in your browser whenever technically practical. Your selected files are not intentionally uploaded to SonoFiles for these local-processing workflows. Each tool page explains its processing behavior.
What file formats are supported right now?
Current live tools support PDF plus common image formats including JPG/JPEG, PNG, WebP, HEIC and HEIF where the specific tool supports them. Always check the selected tool because supported input and output formats differ by task.
Will SonoFiles change my original file?
No. Browser tools create a new result for you to download. They do not overwrite or delete the original file stored on your device.
Do I need an account?
No account is required for the current SonoFiles tools. You can choose a supported file, process it and download the result directly.
What are the file-size limits?
Limits depend on the tool. Current large-file tools generally recommend staying at or below 200 MB for browser reliability and allow up to a 300 MB hard maximum where stated. Some tools also use page-count, image-count, megapixel or dimension safety limits.
Can I use SonoFiles on a phone or tablet?
Yes. SonoFiles is responsive and works on modern mobile browsers. For very large PDFs, large image batches or high-resolution files, a desktop browser is recommended because phones usually have less available memory.
Why can a valid file sometimes fail to process?
A file can be damaged, encrypted, use an unsupported codec or structure, or require more browser memory than the device can safely provide. SonoFiles shows technical limits and error messages rather than claiming a result succeeded when it did not.
