Toolivoo's PDF Compressor helps you reduce PDF file sizes without sacrificing what matters. Whether you need to email a large document, upload a file with size restrictions, or just save storage space, our tool makes it easy. Compression happens entirely in your browser — your file is never uploaded. The smart engine first tries a lossless re-save (which keeps text selectable and works best on text-heavy PDFs), then falls back to re-encoding pages as compressed images for scanned or photo-heavy documents. It aims to reduce file size while preserving useful quality. Results depend on the PDF — scanned and image-heavy files usually shrink the most.
Most online PDF compressors blindly rasterize every page to JPEG — which actually inflates text-only PDFs and destroys selectable text in the process. Toolivoo compresses PDFs directly in your browser using different strategies depending on the selected level. Use Light when you want the highest quality and want to keep text searchable. Use Balanced for everyday documents — the recommended default. Use Maximum for scanned forms, image-heavy PDFs, or anything where you need the smallest possible file size. If your PDF is already well-compressed, the size reduction may be small or there may be no noticeable change.
All processing happens in your browser — nothing is uploaded to our servers.
It depends on what's in your PDF. Scanned documents and image-heavy PDFs typically shrink by 60–80% on Maximum. Text-heavy PDFs may shrink less than scanned or image-heavy files, but can preserve better readability depending on the compression path used. PDFs that are already well-compressed (e.g. previously processed by Adobe Acrobat) may show little or no reduction — in that case the tool returns the original file unchanged so you never end up with something larger than what you started with.
It depends on the level. Light keeps the original PDF structure intact when possible (lossless), so image and text quality is unchanged. Balanced re-encodes images at moderate quality — visually indistinguishable for most uses, including printing. Maximum applies aggressive image compression for the smallest file size; some quality loss may be visible on detailed photos but remains perfectly readable on screen.
It depends on which strategy the tool uses. When the lossless pass produces the smallest file (common for text-heavy PDFs), text stays fully selectable and searchable. When the rasterized pass wins (typical for scanned or image-heavy PDFs), each page is rebuilt as a compressed image, so text is no longer selectable. Depending on the compression method used, text may stay selectable or may be flattened into page images.
The current limit is 50 MB per file. This is enforced to keep processing fast and reliable across devices, since everything runs in your browser's memory. If you have larger PDFs, try splitting them first or use a desktop browser for the best experience.
No — password-protected PDFs must be unlocked before compression. If your PDF has a password, remove it first using a PDF unlocker tool, then compress it here. For security reasons we don't process encrypted documents.
Completely. Your PDF is processed entirely within your browser — it never touches our servers. The file stays on your device throughout the compression process. Once you close the page, all data is cleared from memory. This makes Toolivoo well-suited for sensitive documents like contracts, financial statements, or personal records.
