Yes, all 28+ converter tools on Arriverr are completely free to use. There are no hidden fees, no premium tiers, no watermarks, and no daily usage limits. You can convert as many files as you want, as often as you need.
Are my files safe? Do you upload them to a server?
Your files are 100% safe. Unlike most online converters, our tools process everything directly in your web browser using JavaScript. Your files never leave your device and are never uploaded to any server. This makes our tools the most private online converters available.
What file formats do your converter tools support?
We support a wide range of formats: PDF, Word (DOCX), Excel (XLSX), PowerPoint (PPTX), CSV, HTML, TXT, EPUB for documents; JPG, PNG, WebP, SVG, TIFF, HEIC, ICO, GIF, BMP for images; and Base64 encoding/decoding for developers. Our PDF converter tools alone handle 12 different conversion directions.
What is the maximum file size I can convert?
Since all processing happens in your browser, file size limits depend on your device's available memory. Most modern devices can handle files up to 50-100MB without issues. For very large files, we recommend processing them in smaller batches.
Do I need to install any software?
No installation is needed. All our online converter tools work directly in your web browser (Chrome, Firefox, Safari, Edge). Simply visit the tool page, upload your file, and download the converted result. Works on Windows, Mac, Linux, and mobile devices.
How accurate are the conversions?
Our tools use industry-standard JavaScript libraries (PDF.js, jsPDF, SheetJS, mammoth.js) to ensure high-quality conversions. Text extraction from PDFs preserves content accurately. Image conversions maintain quality with adjustable settings. For complex layouts, some formatting adjustments may be needed after conversion.
