Reduce PDF file sizes by up to 90% while maintaining visual fidelity. Intelligent DSSIM-based quality verification ensures your documents look perfect.
3 Free Compressions • No Credit Card • Windows 10/11
Everything you need to optimize your PDFs, built into one fast desktop application.
4-stage pipeline: analysis, lossless optimization, image optimization with DSSIM quality gate, and verification. Every PDF is handled intelligently.
DSSIM-based perceptual quality checking ensures your compressed PDFs are visually identical to the originals. No guesswork.
Compress multiple PDFs at once. Drag and drop files or browse to select. Parallel image optimization for maximum speed.
Set up watch folders and new PDFs are compressed automatically as they arrive. Perfect for incoming scans and downloads.
From Lossless to Extreme compression. Each preset is calibrated with precise SSIM thresholds and JPEG quality ranges for predictable results.
Create and save custom compression profiles with precise control over JPEG quality, DPI, metadata, font subsetting, and more.
Powerful command-line interface for automation and scripting. Integrate PDF compression into your existing workflows and build pipelines.
All processing happens locally on your machine. Your files are never uploaded anywhere. No cloud, no tracking, complete privacy.
Built with Rust and MozJPEG. Parallel image processing, reduced-resolution search, and Q-min fast path deliver 53x speedup over naive approaches.
Stream deduplication, recompression, ASCII85-to-Flate conversion, and metadata stripping — all without touching image quality.
MozJPEG encoding with binary search quality selection, DPI downsampling, format conversion, and per-image SSIM verification.
Automatically subset embedded fonts to include only the characters used in the document, reducing file size without affecting rendering.
Three simple steps to dramatically smaller PDFs.
Browse or drag-and-drop one or more PDF files. FileMatic analyzes each file to determine the optimal compression strategy.
Pick from 5 built-in presets (Lossless to Extreme) or create a custom profile with fine-grained control over every setting.
FileMatic compresses your PDFs with quality verification. Review results with per-file savings and open compressed files instantly.
Calibrated presets for every use case, from archival quality to maximum compression.
| Preset | Quality (SSIM) | Min DPI | JPEG Range | Best For |
|---|---|---|---|---|
| Lossless | Perfect | Original | N/A | Archival, legal documents |
| High Quality | 0.990 | 200 | 65 – 97 | Print-ready documents |
| Balanced | 0.975 | 150 | 50 – 92 | General purpose (recommended) |
| Maximum | 0.955 | 120 | 35 – 85 | Email attachments, web uploads |
| Extreme | 0.930 | 72 | 20 – 70 | Maximum size reduction |
Get started quickly with the GUI app or integrate via the command-line tool.
Switch to the Auto tab to set up watch folders. New PDFs in watched folders are compressed automatically. Configure per-folder profiles and output destinations.
The Settings tab lets you fine-tune JPEG quality (1–10), target DPI, and toggle options like metadata stripping, JPEG conversion, font subsetting, deduplication, color conversion, and grayscale.
The CLI tool filematic is included with the desktop installer. After installation, it's available in your system PATH.
filematic input.pdf -o output.pdf
filematic input.pdf -o output.pdf --preset balanced
Available presets: lossless, high-quality, balanced, maximum, extreme
filematic input.pdf -o output.pdf --jpeg-quality 80 --min-dpi 150 --strip-metadata
filematic *.pdf --output-dir ./compressed/ --preset maximum
filematic input.pdf -o output.pdf --json
Returns compression stats as JSON for integration with other tools.
Everything you need to know about FileMatic.
FileMatic is a high-performance PDF compression desktop application for Windows. It uses a 4-stage compression pipeline built in Rust with intelligent quality verification to ensure your documents remain visually perfect while dramatically reducing file size.
Depending on the content and preset used, FileMatic can reduce PDF sizes by 30% to 90%. Image-heavy PDFs see the largest reductions. The Balanced preset typically achieves 50–70% reduction while maintaining excellent visual quality.
FileMatic uses DSSIM-based perceptual quality verification on every image. Each preset has a calibrated SSIM threshold — the Balanced preset maintains 0.975 SSIM (virtually indistinguishable). The Lossless preset makes no quality changes at all. You always see per-file quality results after compression.
FileMatic includes 3 free compressions so you can evaluate its performance. After that, a one-time license key unlocks unlimited compressions forever — no subscription, no recurring fees.
No. All compression happens 100% locally on your computer. Your files are never sent to any server. FileMatic only makes a brief network call for license validation — your documents never leave your machine.
FileMatic currently supports Windows 10 and Windows 11 (64-bit). macOS and Linux support are planned for future releases.
Yes! FileMatic offers two automation options: Watch Folders in the GUI automatically compress new PDFs as they arrive, and the CLI tool (filematic) lets you integrate compression into scripts, batch files, and CI/CD pipelines.
FileMatic is built in Rust with several performance optimizations: parallel image processing with Rayon, reduced-resolution quality search, Q-min fast path that skips binary search when possible, baseline JPEG for search iterations, and pre-computed DSSIM references. This results in up to 53x speedup compared to naive approaches.
FileMatic works with all PDFs, but image-heavy documents (scanned documents, presentations, reports with photos, marketing materials) see the greatest size reductions. Text-only PDFs benefit from lossless optimizations like stream deduplication and recompression.
Yes. In the Settings tab, you can adjust JPEG quality (1–10), target DPI, and toggle individual features like metadata stripping, JPEG conversion, font subsetting, color conversion, deduplication, and grayscale. Save your configuration as a named profile for reuse.
