Quick Tips for Enhancing PDFs
Use Grayscale for Text
For text-heavy documents, switching to Grayscale often produces the clearest, most readable results.
Start with Presets
Begin with the '2x (Standard)' enhancement level. If the result isn't strong enough, move to 4x or 6x before fine-tuning with advanced controls.
Check the Live Preview
The "After" window shows your changes in real-time. Use it to find the perfect balance and avoid over-sharpening or making the page too dark.

Frequently Asked Questions
Get instant answers to common questions about our PDF Enhancer tool.
Is it safe to upload my documents to enhance them?
Yes, it is 100% safe. Your privacy is our top priority. The entire enhancement process happens locally in your browser. Your files are never uploaded to our servers, ensuring your data remains completely private.
Will enhancing increase the file size of my PDF?
It can. Because the tool re-renders each page as a high-quality image, the final file size might increase, especially if the original PDF used highly compressed images. We use efficient JPEG compression to keep the final size as reasonable as possible.
What is the difference between the enhancement levels (2x, 4x, 6x)?
The enhancement levels are presets that apply a combination of sharpening and contrast. 2x (Standard) is good for slightly blurry documents. 4x (High Quality) is for average scans. 6x (Maximum) is designed for very poor or faded scans and applies the strongest effect.
Can I undo an enhancement after I have downloaded the file?
The downloaded file is a new, permanently altered version. To undo the changes, you would need to re-upload the original, un-enhanced PDF file and start over. We recommend keeping a copy of your original file.
