Is watermarking PDFs online with AziPDF safe?

Yes. 100% browser-based process — your files are never uploaded to any server.

Can I use my own logo or image as a watermark?

Yes. Switch to Image mode and upload a PNG or JPG. Transparent PNGs work best.

Can I watermark specific pages only?

Yes. Choose "Custom" under page range and enter something like "1-3, 5".

Can I tile the watermark across the whole page?

Yes. Enable "Tile across page" to repeat the watermark in a grid instead of placing it once.

Can I watermark multiple PDFs at once?

Yes. Upload up to 12 PDFs — they'll all get the same watermark and download as a ZIP.

Do I need an account?

No. AziPDF is completely free with no watermarks on the tool itself, no limits, and no signup.

Can I change the watermark's color, size, and angle?

Yes. Text watermarks let you set the font size, color, opacity, and rotation angle to match how visible you want the stamp to be.

Will the watermark reduce my PDF's quality?

No. The watermark is added as a new layer on top of the existing pages — the original content and resolution stay unchanged.

Jinsi ya kufanya

✦

Hatua 3 za haraka za kuweka alama kwenye PDF yako.

Pakia faili zako za PDF

Chagua hadi PDF 12 za kugonga muhuri mara moja, au ziburute na uzidondoshe kwenye kivinjari. Kila faili huchakatwa kwenye kifaa chako, haijawahi kupakiwa kwenye seva.

Chagua maandishi au picha, kisha uifanye mtindo

Andika alama ya maandishi na uweke ukubwa wa fonti na rangi yake, au pakia nembo ya PNG/JPG. Chagua moja ya nafasi 9 au uiweke tile kwenye ukurasa, kisha urekebishe uwazi na mzunguko.

Tuma na upakue

Piga muhuri hati nzima au safu maalum ya ukurasa kama "1-3, 5", kisha upakue papo hapo - PDF moja, au ZIP ikiwa uliweka alama kadhaa mara moja.
