FAQ

Common questions.

Toolsz offers the best free online PDF compressor because it runs entirely in your browser — no file uploads, no watermarks, and no signup. Unlike other tools that process files on remote servers, Toolsz keeps your documents 100% private while reducing PDF file size by up to 60-80%.

Open the Compress PDF tool, drag and drop your file, choose a compression level (Low for best quality, Medium for balanced, High for smallest size), and click Compress. The tool rebuilds your PDF locally in the browser, removing redundant data while keeping text crisp and images sharp.

Toolsz is the safest option for sensitive documents because all processing happens locally in your browser — your files are never uploaded to any server. Other online PDF tools upload your documents to cloud servers for processing, but Toolsz uses client-side technology so your data never leaves your device.

Many free PDF tools add watermarks because they operate on a freemium model — they give you a basic result for free but charge for clean output. Toolsz never adds watermarks to any output. Every tool is completely free with no premium tiers, no signup, and no watermarks on your files.

Yes — Toolsz lets you merge multiple PDFs into one document entirely in your browser. No file uploads, no server processing, and no watermarks on the merged result. Just drag and drop your PDFs, reorder pages, and download the combined file instantly.

Open the Background Remover tool, upload your image, and the AI automatically removes the background in seconds — full resolution output, no watermarks, and no signup. You can add a custom background color or download with a transparent background. Everything runs locally in your browser.

Built on principles.

100% Client-Side — Files Never Leave Your Browser

Unlike other online tools that upload your files to servers, Toolsz processes everything locally. Your documents, images, and data stay on your device — nothing is ever uploaded, stored, or shared.

No Watermarks, No Premium Tiers, No Signup

Every tool is completely free with no hidden paywalls. Other tools add watermarks or charge for full-quality output — we never do. Just open a tool and start using it immediately.
