Frequently Asked Questions

Why was text blurry before and is it sharp now?
We render PDF pages with Retina/high-DPI supersampling (2x–3x device pixel ratio). This ensures every character and vector path is crisp and clear on any display.
Is my document stored on your servers?
No. Everything runs 100% client-side in your browser using pdfjs-dist and pdf-lib. Your confidential documents never leave your device.
Can I add legal signatures to my PDF?
Yes. You can draw your signature, type it using elegant handwriting fonts, or upload a signature image.
How do I erase or redact sensitive text?
Use the Whiteout tool to cover sensitive text, account numbers, or details with an opaque white block before saving.
Can I rotate or reorder pages?
Yes. Use the Rotate button to turn pages 90°, or remove pages using the Delete Page action in the toolbar.

What PDF Editing Can and Can't Do

Edits this tool handles well

PDFs were designed to be final, so editing means layering changes onto a fixed page:

EditHow it worksTypical use
Add textNew text box placed on the pageFilling forms that aren't fillable
Insert imagePlaced and scaled anywhereAdding a logo, photo, or signature image
Shapes and highlightsRectangles, lines, emphasisMarking up a draft for review
Cover contentOpaque shape over existing textHiding an account number before sharing
AnnotateComments and calloutsFeedback on a design or contract

The honest limitation: reflow

A PDF doesn't know its text is made of paragraphs — just characters at coordinates. Deleting a sentence won't pull the next line up, and adding one won't push content down. For light touches — a date, a name, a checkbox — direct editing wins. For rewriting paragraphs, convert with PDF to Word, edit properly, and export back. Knowing which side of that line your edit falls on saves an hour of fighting.

One privacy note on covering text

A shape drawn over text hides it visually, but the text may still exist underneath and can sometimes be selected or extracted. For genuinely sensitive redaction (CNIC numbers, salaries in a shared contract), flatten the result — or print to image-based PDF — so the covered data is gone, not just hidden. For signatures specifically, the dedicated signing tool places them cleanly, and finished edits often end with compression before sending.
