Privacy matters: most tools process files in your browser. Server-processed files are deleted after download or by the short purge window.

PDF tools

Free online PDF tools for everyday documents.

Compress, merge, protect, highlight, split, convert PDF pages to PNG, and extract PDF images from one privacy-focused workspace. Pick the exact PDF tool you need and finish the file task in the browser.

Popular PDF jobs

The most common PDF searches are compress PDF, merge PDF, protect PDF, PDF to PNG, and extract images from PDF. OmniToolbox keeps those workflows separate so users can open the exact tool they need without digging through menus. This matters because a file that needs compression should not be pushed through a converter first, and a document that only needs page extraction should not be merged or re-rendered unnecessarily.

Built for form uploads

Many government, school, job, finance, and application portals require smaller PDFs or one combined document. The PDF tools focus on practical outputs: smaller size, correct order, password handling, preview, and instant download. Before submitting, users should open the final file and verify page count, readability, names, dates, signatures, stamps, and barcodes.

Browser-first processing

Where the browser can safely handle the file, the work stays on the device. Tools that need temporary processing are designed around short retention and clear privacy messaging. This approach keeps the site focused on useful file workflows rather than file galleries, public uploads, or copied content from other sites.

A focused PDF workflow instead of a file dump

The PDF section is organized around jobs that people repeatedly need for school forms, job applications, finance paperwork, certificates, and official uploads. Compression, page ordering, password protection, page images, and image extraction are separate because each task has a different success check. That structure helps users avoid converting or recompressing a document when a simpler PDF operation is enough.

Review the result before submitting

Every important PDF output should be opened once before it is uploaded or shared. Check page count, reading order, small text, seals, signatures, barcodes, and whether password prompts behave as expected. A smaller or merged file is useful only when the final copy still communicates the document clearly.

Choose PDF instead of an image when layout matters

PDF is usually the better format for multi-page documents, printable forms, invoices, certificates, and records that need stable page layout. Convert to PNG only when the receiving website specifically asks for images or when a single page needs to be placed into an image-only field.

Avoid repeated processing

If a file fails a portal rule, return to the original file when possible instead of repeatedly compressing or converting the already-processed output. Repeated processing can add blur, increase file size, or remove useful text while making the file less reliable.

Common questions

Which PDF tool should I use to reduce file size?

Use Compress PDF when a portal rejects a large file or an email attachment is too big. It tries to create a smaller output and avoids returning a larger file.

Can I merge a PDF that asks for an open password?

Yes, when you are authorized to open the document and know the correct password. The password is used only to read that file for the merge.

Can I add a password after merging PDFs?

Yes. After Merge PDF creates the combined file, choose Add password to open Protect PDF with the merged file already loaded.
