How to edit a PDF (4 steps)
- Open the PDF. Tap the box, pick the file (from Downloads, Drive or WhatsApp on a phone). Password-protected files ask for the password; it is used on your device only.
- Pick a tool and tap the page. Add text types new text (switch the font to Urdu for Urdu). Edit text replaces a line of existing text. Whiteout covers a stamp, old date or wrong entry. Highlight, Draw, Box, Arrow mark things. Image adds a photo, Sign your signature, Date, Tick and Cross stamp forms. Blue boxes are real form fields: type straight into them.
- Fix the pages. In the left list: rotate, delete, insert a blank page, drag a page to a new place, tick pages to extract only those. Crop keeps one area of a page.
- Save. Normal PDF (text stays text), flattened (pages as pictures, for privacy or protected files), or under a KB limit for NTS / PPSC / FPSC portals. Then check the file on your phone before you upload it.
What this editor can and cannot do
Online editors are often compared to Adobe Acrobat, Sejda or iLovePDF. Here is the honest list for ours, based on what we built and tested, so you know before you start.
| Task | Here | Notes |
|---|---|---|
| Add new text in English | Yes | Helvetica, Times or Courier, any size and colour, bold. Stays real selectable text in the saved PDF. |
| Add new text in Urdu | Yes | Noto Naskh Arabic is embedded in the PDF; right-to-left, mixed Urdu + English lines. Nastaliq style is not offered (large font, poor results in PDF viewers). |
| Replace a line of existing text | Partly | The line is covered with white and redrawn in the matched size and sampled colour. The font is ours, not the original, so it may look slightly different. Not possible on scanned pages. |
| Whiteout / cover | Yes | Covers only; the text stays inside the file. For real removal use Save flattened. |
| Highlight, underline, strike-through | Yes | Tap a line of text or drag an area. Four highlight colours. |
| Draw, box, circle, line, arrow | Yes | Vector shapes with colour, width and fill; saved as real PDF graphics. |
| Add image (JPG / PNG), signature, date, tick, cross | Yes | Move and resize with the handles. Signature by drawing, typing or photo (white paper made transparent); remembered on the device only. |
| Fill form fields | Yes | Text, multi-line, check boxes, radio buttons, drop-downs of real AcroForm PDFs; flatten on save. XFA forms (some old federal forms) cannot be filled: the page tells you. |
| Rotate, delete, reorder, insert blank, extract, crop pages | Yes | All in the same editor; drag thumbnails to reorder; tick pages to extract. |
| Password-protected PDF | Partly | Opens with the password and can be edited, but the browser cannot rewrite encrypted pages, so saving gives a flattened (picture) PDF. |
| OCR, links, find and replace, true redaction | No | OCR is in PDF to Word. Redaction that removes content is only guaranteed by Save flattened. |
| Files over 25 MB or 60 pages | No | Everything runs in the phone's memory. Compress or split the file first. |
Typical uses in Pakistan
- Fill a job application form issued as a PDF: type on the lines, tick boxes, add your photo and signature, then save under 200 KB for the portal with Compress PDF or the KB option here. Check the age limit first with the age calculator.
- Correct a CV you only have as a PDF: whiteout the old phone number or date, add the new one in the same size. For bigger changes convert it with PDF to Word or rebuild it with the CV Builder.
- Sign and date an affidavit, undertaking or NOC before uploading, without printing and scanning.
- Prepare documents for a portal: rotate a sideways scan, delete a blank page, put CNIC, degree and domicile in the right order, or extract only the pages they ask for (or use Merge PDF for several files).
- Mark a notice or past paper for study: highlight, underline and draw arrows, then save.
Why no online editor edits PDF text perfectly
A PDF stores each letter at a fixed position with only the glyphs that the document uses, not the whole font. To change a word, an editor has to hide the old letters and draw new ones; it cannot "type into" the page like Word. Desktop Acrobat does this with the original font when it is installed on the computer; a browser does not have that font, so it uses a similar one. That is why every online editor, including this one, says the font may differ after editing. For long edits, convert to Word, edit there and convert back.
Frequently asked questions
All answers, in full:
How do I edit a PDF online for free without uploading it?
Open this page, tap Choose a PDF and pick the file. The pages appear in your browser. Use the toolbar to add text, cover parts with whiteout, highlight, draw, add an image or a signature, fill form boxes, and rotate or reorder pages. Press Save and the edited PDF downloads. The file never leaves your phone or PC: the editor is JavaScript running on your device, there is no server, no account and no watermark.
Can I change the existing text in a PDF?
Partly, and we are honest about it. Choose Edit text, tap a line, and type the new words. The old line is covered with a white box and the new text is drawn in the same size and colour. The font is Helvetica, Times, Courier or Noto (Urdu) rather than the original, because PDFs carry only the letters they use and no editor can re-flow a page in the browser. On scanned or photographed PDFs there is no text to tap: use Add text on top instead.
Does it support Urdu?
Yes. Choose the Urdu / Arabic (Noto Naskh) font or just start typing Urdu: the text box switches to right-to-left and the saved PDF embeds the Noto Naskh Arabic font, so the Urdu shows correctly on every device. Mixed Urdu and English in one line works too. Two honest limits: Urdu typed into an existing form field is not supported (the field font is fixed by the form), so add text on top of the field instead; and copying Urdu text back out of the saved PDF can give broken letters in some viewers, although it displays and prints correctly.
Can I fill a government application form PDF?
If the form has real fillable boxes (PPSC, FPSC, NTS and bank forms often do), they appear as blue boxes: tap and type, tick boxes, pick from drop-downs. When saving, keep Flatten form fields ticked so the answers are locked. If the form is only a printed page (no boxes), use Add text to write on the lines, Tick for check boxes and Image for your photo.
How do I sign a PDF?
Choose Sign. Draw your signature with a finger or mouse, type your name in a handwriting style, or upload a photo of your signature (the white paper is made transparent). Then tap where it goes and drag a corner to resize. The signature is remembered in your browser only, never uploaded, and you can delete it with "Make a new signature".
Does whiteout remove the text underneath?
No. Whiteout covers the area with a box in the saved PDF; the original text is still inside the file and could be found by copying or by removing the box. For CNIC numbers, salaries or anything private, use Save flattened, which turns every page into a picture, so the covered text is truly gone.
What are the limits and does it work on a phone?
25 MB and 60 pages per file, because everything runs in the browser's memory. On phones the toolbar sits at the bottom, you pinch to zoom, drag with one finger to move things and tap the page icon to open the page list. Your edits are autosaved on the device: if the tab closes, open the tool again and press Continue.
Which save option should I choose?
Save PDF keeps the original pages as they are (text stays selectable, smallest file) and adds your edits as real PDF content. Save flattened draws every page as a picture: use it for privacy, for password-protected PDFs, or when a portal rejects the normal file. Save under a KB limit gives the same result as our Compress PDF tool, for the 200 KB / 500 KB limits of NTS, PPSC and FPSC portals.
