- How many images can I combine?
- Up to 50 images in one PDF.
- Can I use PNG or HEIC photos instead?
- This tool accepts JPG images. Photos from an iPhone saved as HEIC need to be exported as JPG first.
- Are the images compressed when they become a PDF?
- The JPGs are embedded as they are, so the pages look exactly like your original photos. If the result is large, run it through the compress tool afterwards.
- Are my files uploaded to a server?
- No. Every tool on this site runs inside your browser tab using WebAssembly. Your file is read from your disk into the tab's memory, processed there, and written back out as a download. It is never sent over the network, so there is no server copy to leak, subpoena, or forget to delete.
- Do I need to create an account?
- No. There is no signup, no email, and no login on any tool. You can use every tool an unlimited number of times without identifying yourself.
- Is there a file size limit or a daily limit?
- There is no daily limit and no artificial size cap. The real ceiling is your device's memory: roughly 200-500MB per file on a desktop, and closer to 50-100MB on a low-end Android phone. Past that the browser tab can run out of memory.
- Is the output watermarked?
- No. Output files are clean. Nothing is stamped on them, and no page is added.
- Does it work on a phone?
- Yes. The tools run in any modern mobile browser, including Chrome on Android and Safari on iOS. Large files are slower on a phone than on a laptop because the processing happens on the device itself.
- Does it work without an internet connection?
- You need a connection to load the page the first time. Once the page has loaded, the actual PDF processing needs no network at all — you can turn off your Wi-Fi before pressing the button and the tool will still work.
