About This Tool

Tax season runs on PDFs: W-2s from every employer, 1099s from every client, prior returns, receipts — and e-file portals plus accountants cap uploads hard. A single scanned 1099 can blow past a 10MB limit on its own. This tool compresses tax documents while keeping every figure legible, entirely in your browser, so sensitive financial paperwork never touches a server.

How It Works

Three simple steps to get your optimized PDF.

Drag and drop or browse to select your PDF file. Files are processed locally and never leave your device.

Choose Compression Level

Pick Low, Medium, or High compression. Higher levels produce smaller files while keeping text and layout readable.

Frequently Asked Questions

How large can tax upload attachments be?

IRS e-file and most preparer portals cap attachments between 5 and 128MB depending on the form, but individual documents should stay small. Under 5MB per file clears virtually every tax upload.

Will compression blur numbers on my W-2?

Not at Medium compression — printed figures stay sharp because PDF text is vector. Scanned forms need a check at full zoom; use High only when a portal demands tiny files.

Is it safe to compress tax documents online?

Here, yes: everything runs locally in your browser, so W-2s and returns with Social Security numbers are never uploaded anywhere. That is precisely why browser-based tools suit tax paperwork.
