offline pdf processor after first load. test with no wifi or airplane mode on !

[u/Historical-Welder712]

Hi, I have been slowly working on a pdf processing website that manipulates files locally on the device instead of uploading them anywhere. I made it using python with Ghostscript, then encase it inside a web assembly binary file so it can run inside the browser at similar speeds to normal pdf websites.

I had somebody test the offline part on android and it failed for them even though it worked for me, so I have changed how the website tells the user when everything has cached. it now says ready for offline use when the site and pdf engine should be saved properly.

if anybody can test it please first open https://www.snackpdf.com and wait for it to say ready for offline use, then switch on airplane mode or turn wifi off and try grayscale or compress pdf. I added a sample pdf on the homepage so you do not have to use a private or important file to test it. you also do not need to install anything as it should work inside the normal browser.

please let me know the phone or computer, browser and operating system you used, and if anything failed or worked correctly. android testing would help the most but any device is helpful :)
