Add an image to a PDF
Drop a logo, a photo or a stamp onto any page. windpdf inserts it at its natural aspect ratio, never stretched, and lets you place it precisely before saving.

Files stay private: PDFs and images are edited in your browser.
Aspect ratio preserved
Images are inserted at their natural proportions and scaled down to fit the page, never upscaled beyond their own pixels, never distorted.
PNG and JPG
Both formats are embedded natively, so transparency in a PNG logo survives the round trip.
Runs in your browser
Your file is processed on your device and only uploaded if you choose to save it to your drive.
A logo, placed by hand
Drop a PNG or a JPG on the page: it lands at its natural proportions with the same handles as every other object.
Place it, then nudge it
The image comes in scaled to fit and stays selected: drag it, resize it from any handle, delete it. Nothing is committed until you save.
Never stretched, never upscaled
The natural aspect ratio is preserved, and large images are scaled down rather than enlarged past their own pixels.
A signature is an image too
The signature dialog takes the same files: draw one, type one, or upload the PNG you already have on disk.
Photos are where the megabytes hide
An image-heavy document grows fast. Compress re-encodes the images and leaves the text sharp: on a 26-page office document we measured 6.4 MB down to 2.4 MB.
Logos, stamps and photos in one click
Brand a document with your logo, attach a photo to a report, or drop a "PAID" stamp on an invoice. The image lands on the page at a sensible size and you drag it to its final place.
Images are added as standard PDF image objects: they print at full quality and show up in every viewer.

Frequently asked questions
PNG and JPG. A PNG keeps its transparency, which is what you want for logos and stamps.
No. The natural aspect ratio is always preserved, and large images are scaled down, never enlarged past their own resolution.
Yes, until you save the document: drag it, resize it or delete it like any other object.
