Content reviewed October 2026 · About Toolzum
Trims PDF file size by stripping redundant metadata and optimizing object streams — best on text-heavy documents. Cannot recompress embedded images (the main size driver); for scan-heavy PDFs use Bulk PDF Size Reducer. Handles PDFs up to 125MB.
Pull every embedded image from a PDF at native resolution — photos, charts, logos. Recover 40 figures from a report without screenshots — local PDF.js work, unlimited saves.
Inserts page number labels at user-chosen positions (bottom-center, top-right, etc.) with configurable font, size, and starting offset. Documents stay on your device — editing and conversion run locally in your browser.
Decode QR codes from uploaded images. Scan any QR code image and extract the embedded text or URL. Point it at screenshots, photos, or documents — decoded URLs and text copy out instantly. Runs locally, free, no signup.
Convert ICO favicons to editable PNG in your browser — extract icon artwork at full embedded size for reuse in any editor.
Any — images, spreadsheets, archives, documents. The PDF carries them as embedded payloads.
Yes — embedded files travel inside the PDF through any mail system intact.

No — embedding runs locally in your browser; unlimited saves on local tools.
