Frequently asked questions

Is Image to Base64 free?

Yes. There's no sign-up, no watermark and no usage limit.

Are my files uploaded to a server?

No. Image to Base64 runs entirely in your browser. Your files never leave your device and nothing is stored — close the tab and everything is gone.

Which file types can I use?

JPG, PNG, WEBP, GIF, BMP, TIFF, HEIC, SVG, ICO. Files are checked by their actual content, not just the extension, so renamed or damaged files are caught early.

Is there a file size limit?

Each file can be up to 200.0 MB, and you can process up to 5 files at once. Because processing uses your device's memory, very large files work best on a computer.

Does it work on my phone?

Yes. It works in modern mobile browsers on Android and iPhone. Heavier jobs (large PDFs, OCR) are faster on a computer.
