About PDF Despeckle
Old or low-quality scans often come out covered in tiny black dots, specks, and background noise. Those stray marks make text harder to read, bloat the file, and can confuse OCR. Despeckling cleans them away, leaving a crisper, clearer scanned page.
The tool examines each page and removes the small isolated dots and noise while keeping your actual text and lines intact. It all runs in your browser, so your documents stay private on your own device. It's free, needs no signup, and never stamps a watermark on your pages. The result is a cleaner scan that reads better and looks more professional.

FAQ
Will despeckling erase small punctuation or fine detail?
It targets isolated noise dots, not connected text. Very fine marks can occasionally be affected, so check the result on detailed pages.
Does this work on color scans?
It's most effective on black-and-white or grayscale scanned text, where speckle noise is most visible.
Can it reduce the file size too?
Often yes. Removing scattered noise can make scanned pages compress more efficiently.
Can I use PDF Despeckle on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
