Frequently Asked Questions
Are these PDF tools really free?▾
Yes - every PDF tool on this page is free with no signup, no watermarks on output and no daily usage caps. All processing runs locally in your browser, so your files are never uploaded.
Which PDF tools work without uploading my file?▾
All of them. Compression, merging, splitting, rotating, watermarking, page deletion, reordering, signing, page numbers, text extraction and conversions like PDF to JPG or JPG to PDF all run entirely in your browser. To convert Word, Excel, PowerPoint or HTML files into a PDF, use the Convert category.
Can I edit an existing PDF's text?▾
The Edit PDF tool lets you add text boxes, images, drawings and highlights anywhere on a page. Rewriting embedded paragraph text is different - extract the text first if you need the raw content.
What is the maximum file size I can process?▾
Tools handle large documents limited mainly by your device memory - typically hundreds of megabytes for browser-based jobs.
