PDFly's New Compression Engine: 40% Better Results

We've been working hard on **pdfly** improvements, and this update delivers significant gains. Faster processing, better **compression** quality, new features you've been asking for, and the same privacy-first approach that makes PDFly different from every other PDF tool. Here's the full breakdown.

Quick summary

Technical update on the new compression algorithm delivering smaller files.

What's coming next for pdfly at PDFly

For **pdfly** users who process files daily, the cumulative time savings from this update are significant. If you process 20 compression files per day, the 3x speed improvement saves you approximately 15 minutes per day — over 60 hours per year. That's real, measurable productivity gained from a free update.

Privacy hasn't changed in this **pdfly** update because it was already perfect: zero file uploads, zero tracking, zero data collection. But we've made it easier to verify. The updated UI includes a privacy indicator that shows "Processing locally" during every operation, with a link to verify in the Network tab.

• Processing a 100MB pdfly: previously 8 seconds, now 2.5 seconds
• Compressing a 50MB compression: previously 15MB output, now 9MB average
• OCR on a 20-page scanned pdfly: previously 30 seconds, now 10 seconds
• Merging 50 compression files: previously 45 seconds, now 12 seconds
• Memory usage during pdfly processing: reduced by 40%

What users are saying about the compression changes

Performance is where this **pdfly** update shines. We've rewritten core processing routines in optimized WebAssembly, reducing processing time by 3x across all tools. A 100MB compression file that took 8 seconds now processes in 2.5 seconds. Memory usage dropped 40%, meaning you can handle larger files on the same hardware.

This **pdfly** update is the result of months of development and direct user feedback. We analyzed the most common workflow bottlenecks and focused our efforts on the changes that make the biggest difference. The result: faster compression processing, new capabilities, and a cleaner interface.

What's new in this pdfly update

We measure **pdfly** update success by one metric: does it save users time? Based on early testing with 500 users, this update reduces average task completion time by 65%. That's not a marginal improvement — it's a generational leap in browser-based compression processing.

The **pdfly** update is available immediately. No download, no installation, no migration. Just refresh the PDFly page and you're on the latest version. Your bookmarks, settings, and workflows all work exactly as before — just faster.

Privacy and security in this update

Privacy hasn't changed in this **pdfly** update because it was already perfect: zero file uploads, zero tracking, zero data collection. But we've made it easier to verify. The updated UI includes a privacy indicator that shows "Processing locally" during every operation, with a link to verify in the Network tab.

The new **pdfly** features in this update were driven by user requests. We tracked the most-requested capabilities on our feedback form and built them. Every feature maintains our strict privacy-first commitment — 100% client-side processing, no file uploads, no tracking.
