Private PDF tool

Every PDF tool you need, completely private

PDFOmni is a local-first PDF toolkit for everyday document work. Files stay on your device while the browser handles merge, split, compress, convert, edit, sign, protect, unlock, and accessibility workflows.

Merge, split, compress, convert, edit, sign, and protect PDFs locally in your browser with private client-side PDF tools.

Private PDF tools for real document work

PDFOmni is built for people who need practical PDF tools without sending every file through an upload-first server workflow. The app covers common document jobs such as merging, splitting, compressing, converting, editing, signing, protecting, unlocking, redacting, and checking PDFs for accessibility.

The homepage is organized around real document tasks, so you can search by tool name, browse by category, and open the exact workflow you need without digging through unrelated options.

Core PDF processing is designed to happen locally in the browser wherever the selected workflow supports it. That matters for private files such as school documents, invoices, resumes, reports, contracts, scanned forms, and internal business PDFs.

Organize & Optimize tools

Use these tools when a PDF needs basic cleanup before you send it, print it, or archive it. Merge related documents into one file, split out only the pages you need, reorder messy packets, compress large attachments, rotate sideways scans, or add page numbers for reports and submissions.

In this category you can use Merge PDF, Split PDF, Reorder Pages, Compress PDF, Rotate Pages, and Page Numbers. Each link opens a dedicated page with the actual browser tool, a simple upload flow, and more detail about the specific PDF task.

• Merge PDF - Combine multiple PDFs into one
• Split PDF - Split a PDF by page ranges
• Reorder Pages - Drag and drop to rearrange pages
• Compress PDF - Reduce file size without losing quality
• Rotate Pages - Rotate individual or all pages
• Page Numbers - Add page numbers to your PDF

Convert to PDF tools

Turn everyday files into PDFs when you need a format that is easier to share and review. Word documents, spreadsheets, image files, and HTML pages can become cleaner PDF outputs for school work, client documents, invoices, forms, portfolios, and web content.

In this category you can use Word to PDF, Excel to PDF, Image to PDF, and HTML to PDF. Each link opens a dedicated page with the actual browser tool, a simple upload flow, and more detail about the specific PDF task.

• Word to PDF - Convert DOCX files to PDF
• Excel to PDF - Convert spreadsheets to PDF
• Image to PDF - Convert JPG/PNG images to PDF
• HTML to PDF - Convert HTML pages to PDF

Convert from PDF tools

Pull useful content out of a PDF when the document needs to move into another workflow. Export pages as images for previews and thumbnails, or extract text from a PDF so it can be copied into notes, research drafts, email replies, or document archives.

In this category you can use PDF to Image, and PDF to Text. Each link opens a dedicated page with the actual browser tool, a simple upload flow, and more detail about the specific PDF task.

• PDF to Image - Export pages as JPG or PNG
• PDF to Text - Extract all text content

Edit & Annotate tools

Edit and annotate tools are for documents that need visible changes before they are shared. Use the world-class Edit PDF workflow to modify PDF text, add watermarks, redact sensitive details, crop unwanted margins, draw attention to important areas, or adjust embedded images without starting the document again from scratch.

In this category you can use Edit PDF, Add Watermark, Redact, and Crop Pages. Each link opens a dedicated page with the actual browser tool, a simple upload flow, and more detail about the specific PDF task.

• Edit PDF - World-class text and image editing
• Add Watermark - Stamp text watermark on pages
• Redact - Black out sensitive information
• Crop Pages - Crop page dimensions

Security tools

Security tools help with private documents such as invoices, bank statements, contracts, school records, and signed forms. You can protect a PDF with a password, unlock files you are allowed to open, or add a signature before sending the document to someone else.

In this category you can use Protect PDF, Unlock PDF, and Sign PDF. Each link opens a dedicated page with the actual browser tool, a simple upload flow, and more detail about the specific PDF task.

• Protect PDF - Add password protection
• Unlock PDF - Remove password protection
• Sign PDF - Add digital signature

Advanced tools

Advanced tools are useful when a one-off PDF action is not enough. Batch processing helps repeat the same document steps across multiple files, while the WCAG checker helps review accessibility issues before a PDF is published, submitted, or shared with a wider audience.

In this category you can use Batch Process, and WCAG Check. Each link opens a dedicated page with the actual browser tool, a simple upload flow, and more detail about the specific PDF task.

• Batch Process - Process multiple PDFs at once
• WCAG Check - Scan for accessibility issues

Why PDFOmni focuses on local processing

Many PDF websites work by uploading the file first, processing it on a remote server, and then sending the result back. PDFOmni takes a local-first approach so tools can create the output inside the browser tab. That makes the experience useful for people who care about privacy, speed on large files, and not waiting for a server queue.

PDFOmni sets a clear 500 MB per-file limit for PDF tools. Browser performance still depends on the device, file complexity, image resolution, fonts, forms, and page count, but the limit gives users a straightforward boundary before they choose a file.

The site is free to use and does not add artificial rate limits to local browser actions. When a document needs multiple steps, users can move from one PDFOmni tool to another, or use the workflow builder for repeatable document tasks.

Compared with upload-first services, PDFOmni is built to be one of the best choices for privacy-focused PDF work. Its world-class Edit PDF tool goes beyond simple page overlays: true PDF stream editing within the browser can work with selectable text, embedded-font data, images, and document objects while keeping the source file on the device.
