Quick answer

What does Edit PDF do?

NoLogPDF is a free browser-based PDF editor for changing detected text, adding or replacing images, inserting signatures and form fields, and recognizing scanned text with local OCR. Your PDF stays on your device, and the edited copy is created in your browser without a file upload or account.

Use Edit PDF when you need to edit PDF text, images, forms, signatures, and page content locally in a browser. Common uses include correct a name, date, amount, or sentence in a PDF, add or replace a logo, photo, signature, or stamp, turn a scanned page into editable OCR text, add fillable text fields, checkboxes, radio buttons, and dropdowns.

Designed around the task

Why use Edit PDF?

Focused controls, local processing, and clear limits help you finish the job without sending the document to a conversion server.

Focused results

Covers edited source text and writes the replacement into a new PDF copy.

Useful browser controls

Can move following detected text in the same column when an edited text box grows or shrinks.

Desktop and mobile

Use Edit PDF in a current desktop or mobile browser without installing a separate app.

Simple local workflow

Can add images, signatures, markup, shapes, comments, stamps, and interactive form fields.

Private by design

The selected PDF is processed by JavaScript running in this browser for Edit PDF. NoLogPDF does not send it to a backend conversion API, and file names, contents, form values, passwords, and output data are excluded from site analytics.

Automatic file recognition

NoLogPDF checks the selected file in your browser and shows the controls available for Edit PDF.

How to use Edit PDF

Choose a PDF file and open Edit Text.
Select detected text or run local OCR for a scanned page.
Change, add, or remove words; adjust font, size, color, alignment, and text flow.
Add or replace images, signatures, shapes, comments, or form fields, then save the new PDF.

Browser-only privacy

Limits to know before using Edit PDF

PDF pages use fixed coordinates, so automatic text flow is an approximation and cannot reproduce every Word-processing layout.
OCR accuracy depends on scan quality, language, rotation, and font clarity; review OCR text before saving.
A source font that is not browser-embeddable may be replaced with a standard PDF font.

Practical guidance

Edit fixed-layout PDF content with fewer surprises

A PDF stores page objects at fixed coordinates, so editing is different from typing in Word. Start with detected text for a digital PDF and use OCR only for scanned pages. Keep text-flow enabled when a correction changes the length of a line, then inspect nearby headings, columns, and page breaks before downloading.

Recommended workflow

Use the detected-text view to select the exact line or text box you want to change.
Match the font, size, color, and alignment before replacing longer text.
Use image replacement for an existing logo or photo and image insertion for new artwork.

Check the result

Zoom in and confirm that covered source text is no longer visible behind the replacement.
Review every page affected by text flow, OCR, forms, signatures, or image changes.
Open the downloaded copy in a second PDF viewer before sending an important document.

Common uses for Edit PDF

Correct a name, date, amount, or sentence in a PDF.
Add or replace a logo, photo, signature, or stamp.
