Understand

Reduce a document's size directly on your device

You shrink PDFs to email them, free up space, or stay within a size limit — without uploading files online. The tool lets you optimize a PDF, combine multiple files, or split a large document, all on your computer or phone.

What 'in your browser' means

  • Your PDFs stay on your computer
  • No data is transmitted to our servers
  • Processing is instant
  • No trace left behind
After the tool

Send the result: standard mode or Explore mode

When your file is ready on your device, send it with FileVert Transfer from the built-in send action. Choose whether the recipient downloads immediately (standard) or previews first in the browser without a silent local copy (Explore mode).

Standard mode

Secure link: the recipient downloads the file in the usual way. Best for final deliverables, archives and heavy attachments.

Guide: send very large files

Explore mode

Let someone read and page through a PDF in the browser without a silent on-disk copy.

Guide: read-only PDF in the browser

A true combined PDF workflow, locally

FileVert is not limited to one action per file. You can combine several PDF steps in a single run: shrink file size, merge documents, split pages, strip metadata (GDPR), and add a watermark. These steps work in batch on whole folders, with folder structure preserved, all running locally in your browser — no cloud, no server, no third-party analysis.

Compress a PDF without visible quality loss

FileVert shrinks PDF file size right in your browser, with no upload to a third-party server. Compression focuses on embedded images while keeping text, layout, and readability for screen viewing or light printing.

Compressing embedded images

Heavy PDFs usually come from unoptimized high-resolution images. FileVert recompresses those images locally, without changing text or layout.

Compression without visible quality loss

Settings are tuned to keep text readable on screen, for light printing, and for email sharing. Text stays selectable.

Compress a scanned PDF

Scanned documents often produce very large PDFs. Local compression keeps sensitive admin or medical files on your device.

Merge multiple PDFs into one document

Combine several PDFs into a single file, without artificial free-tier limits like “two files only.” Merging runs locally — your files never pass through a third-party cloud before export.

Merge PDFs with no file count limit

Unlike many online tools that cap free plans at 2 or 3 files, FileVert merges as many PDFs as you need in one operation.

Merge a full folder of PDFs

Import an entire folder: every PDF inside can be merged into one document.

Merge + compress in one step

Combine merging and compression to get a lightweight final document with no extra step.

Split a PDF or extract pages

Break a large PDF into several files or pull out only the pages you need. Splitting and shrinking can be chained so you share just the relevant part of a document.

Split a PDF into several documents

Divide a large PDF into parts using defined page ranges.

Extract specific pages

Keep only useful pages (signature, appendix, form) without sending the full document.

Split + compress for quick sharing

Send only the useful portion of a document, in a smaller file.

Clean a PDF: remove sensitive metadata

Every PDF carries metadata by default: author, software, dates, edit history, and sometimes location hints from mobile exports. A résumé can expose a Windows username; a contract can show who edited it and when. FileVert strips this information locally, without sending the file to a third-party server.

Remove author, dates, and edit history

FileVert clears technical metadata before export.

Anonymize a PDF before publishing

To share a document online without revealing its technical origin, metadata cleaning is essential.

GDPR compliance for shared documents

GDPR requires minimizing personal data. Local cleaning stops metadata (author name, organization, machine) from leaking unintentionally.

Add a watermark to a PDF

Apply a text or image mark to PDFs before sharing or archiving. Watermarking can be combined with compression or merging in the same local workflow.

Text watermark (CONFIDENTIAL, DRAFT, DO NOT DISTRIBUTE)

Quick marking for internal or draft documents.

Image watermark (logo, stamp)

Custom visual marking for official or branded documents.

Most common use cases

Compress a PDF for email

Mailboxes often cap attachments at 10 or 25 MB. Shrinking a large PDF helps you stay within those limits without splitting the send into several emails.

Build a complete file by merging PDFs

Job applications, admin bundles, theses, reports: merging parts into one document makes sending and reading easier.

Clean a confidential PDF before sharing

Contracts, quotes, payslips, medical records: removing metadata avoids leaking sensitive technical details.

Extract part of a long document

Pull out only the useful section of a report, ebook, or admin file.

Prepare an official document with watermark and compression

Add a “CONFIDENTIAL” watermark or logo, then compress — all in one pass.

Combine multiple PDF actions in a single pass

Shrink + clean PDFs (optimization + GDPR)

Merge + compress multiple files

Split + optimize large documents

Merge + compression + watermark for confidential documents

Full workflow: merge, shrink, clean, and mark

Frequently asked questions

Everything you need to know about the FileVert PDF compressor

How do I compress a PDF for free without uploading it online?

Open the FileVert PDF compressor in your browser, import your files, and run the job. Everything runs locally on your machine — no PDF is sent to a third-party server. The tool is free and needs no account.

How do I reduce PDF file size for email?

Choose compression mode, import the PDF, and process it. FileVert mainly optimizes embedded images, which often brings the file under typical attachment limits (10 or 25 MB) without splitting the email.

Can I compress a PDF without losing quality?

Yes, for practical screen reading and light printing. Settings preserve readable text and layout; text remains selectable after processing.

How do I compress a scanned PDF?

Import your scanned PDF like any other file. Local compression targets heavy page images while keeping the file on your device — useful for admin or medical documents.

Is there a size limit for PDF compression?

FileVert accepts up to 100 PDFs per session, 200 MB per file, and 2 GB total per run. Beyond that, split your batch or process folders in several passes.

How do I merge several PDFs into one document?

Turn on merge mode, add all PDFs to combine (no “two files on free plan” cap), and run the job. You get one document, generated locally in your browser.

Can I merge a full folder of PDFs with no limit?

Yes. Import a whole folder: every PDF inside can be merged in one operation, with folder structure kept for batch exports.

How do I merge and compress PDFs in one step?

Combine merge and compression in the same FileVert workflow. You group your files and get a lighter final document with no cloud upload in between.

How do I split a PDF into several files?

Use split mode: set page ranges or split by parts. FileVert creates several PDFs from the source file, always processed locally.

How do I extract specific pages from a PDF?

In split mode, select only the pages you need (signature, appendix, form). You get a file with just those pages, without sending the full original.

How do I remove PDF metadata?

Enable clean mode before export. FileVert removes author, dates, edit history, and other technical metadata without sending the file to a server.

How do I anonymize a PDF before sharing?

Process the file with clean mode, then export or transfer it. Technical traces (software, machine, author) no longer travel with the shared file.

How do I clean a PDF for GDPR compliance?

Local cleaning removes embedded personal or organizational metadata (author name, organization, machine). It complements your data-minimization practices before sharing, especially for documents containing HR, medical, legal, or financial data.

Do I need an account to use the FileVert PDF compressor?

No. The tool works right away with no sign-up. You can process, download, and optionally transfer PDFs via FileVert.

How do I process a full folder of PDFs with its structure?

Import a folder in folder mode: FileVert processes PDFs in batch and keeps subfolder structure on export (ZIP or transfer). Ideal for client, admin, or multi-part project folders.
