Frequently asked questions
Are my images uploaded to a server?
No. The PDF is built entirely in your browser, so your images never leave your device — nothing is uploaded and nothing is stored.
Which image formats can I use?
JPG and PNG are embedded directly; WebP, GIF, and BMP are decoded by your browser and included too. You can mix formats in one PDF, and reorder the pages before you download.
Can I choose the page size?
Yes — put each image on an A4 or US Letter page (scaled to fit, with an optional margin), or choose “Fit to image” to make each page exactly the size of its image.
Is there a limit on how many images?
You can add up to 50 images, up to 50 MB in total, per PDF. Everything is processed locally, so larger batches simply take a little longer on your device.
