Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.
Fix a photo for an upload form →Images → PDF
Combine a batch of images into one PDF, one image per page.
Combine a set of images — photos of a document, receipts, screenshots — into a single PDF, one image per page, in the order you choose. Handy when an upload asks for 'a PDF' but all you have is phone photos.
How Images → PDF works
- Drop your files into the tool, or click to browse.
- Everything runs in your browser — no upload, no server, no waiting.
- Download your result straight to your device.
Good to know: Each image becomes its own page at its own size, so for a tidy uniform document make sure the photos share an orientation and roughly the same dimensions before combining.
