About This Tool
An oversized PDF is almost always an image problem. A phone photo of a document lands at 4,000 pixels wide, gets embedded at full resolution, and a three-page file balloons to 30 MB. The text itself contributes almost nothing.
Compression here works on the images: they are downsampled to a sensible DPI for reading or printing and re-encoded, while the text layer and vector graphics are left alone. Unused objects, orphaned fonts and stale metadata get dropped too, which often accounts for a surprising amount of a file grown over many edit-and-resave cycles.
You choose the trade-off. Low compression is safe for anything going to a printer; high is for email attachments and web upload forms where a slightly softer scan is fine. The tool reports both sizes so you can judge whether the result was worth it.
How to Use
Add your PDFs
Drop in up to 10 files. Each is compressed independently with the same settings.
Pick a quality level
Low for print-safe savings, medium for general use, high when you need to hit an attachment limit.
Compress and compare
The result shows original size, new size and the percentage saved before you download.
Use Cases
Getting past an email limit
A 28 MB scanned lease will not send. High compression typically brings that under 5 MB with the text still legible.
Publishing to a website
A brochure that loads in two seconds instead of fifteen, because the images no longer carry print resolution nobody will use.
Cleaning up after many edits
A file edited and resaved twenty times carries dead objects. Compressing rebuilds it and drops the debris.
Frequently Asked Questions
How much smaller will my file get?
It depends entirely on what is inside. Image-heavy scans often drop 60-90%. A text-only PDF may barely change, because there was nothing bulky to remove.
Will the text get blurry?
No. Text is stored as vectors and fonts, not pixels, and is not touched. Only embedded images are downsampled.
Can I still print the result?
At low or medium settings, yes. High compression targets screen reading, so a large-format print may show softness in photos.
Is compression reversible?
No. Image data that is thrown away is gone, so keep your original if you may need the full-resolution version.
