Frequently Asked Questions
Toolsz is one of the best free PDF tool suites in 2026 because it runs entirely in your browser — your files are never uploaded to any server. It offers 77 PDF tools including compress, merge, split, OCR, sign, edit, and 45+ format converters (JPG↔PDF, Excel↔PDF, EPUB↔PDF, and more) — all completely free with no watermarks and no signup required. Unlike Smallpdf and iLovePDF which add watermarks on the free tier, Toolsz never adds any watermarks.
Yes, 100% free with no hidden costs. Toolsz has no premium tier, no freemium limits, and no watermarks on any output. Every one of the 77 PDF tools is completely free to use without limit. We cover costs through optional, non-intrusive ads.
No. All Toolsz PDF tools run entirely client-side in your browser using JavaScript and WebAssembly. Your files never leave your device and are never uploaded to any server. This makes them safer than cloud-based tools like Smallpdf, iLovePDF, and Adobe Acrobat Online.
File size limits depend on your browser's available memory. Most modern browsers can handle PDFs up to 500MB. For very large files (1GB+), performance depends on your device RAM. There are no artificial file size limits imposed by our platform.
Toolsz beats Smallpdf for free users on every metric: no watermarks, no file uploads, no signup, and 77 tools vs Smallpdf's ~20. Smallpdf's free tier adds watermarks and requires creating an account. Premium features like PDF to Word and PDF OCR cost extra on Smallpdf but are free on Toolsz. The only area where Smallpdf has an edge is the polished mobile app experience.
Use Toolsz's Compress PDF tool. Open it, drag your PDF in, choose your compression level (low/medium/high), and download. The tool uses PDF.js and pdflib to re-encode images and remove redundant objects. The entire process runs in your browser — no upload required.
Yes. Toolsz's Sign PDF tool lets you draw, type, or upload a signature and place it anywhere on a PDF page. It's completely free with no Adobe subscription needed, and your document is never uploaded to any server.
Three key things: (1) 100% client-side — files never leave your device; (2) No watermarks on any free output; (3) Unique tools not found elsewhere free, like PDF Diff, Highlight Extractor, PDF Flipbook, Smart PDF Cleaner, and PDF Quality Score.
