I need to shrink a PDF down to about 900kb using just my Android phone since I don’t have a laptop handy. The upload portal rejects anything bigger and the apps I tried barely help. Any suggestions? ---

That is annoying when a portal has a hard size limit. I would open the PDF from Google Drive into Google Docs, then export as PDF, since Docs rebuilds and often trims it. If still too large, use the Android print option and choose Save as PDF, because that usually compresses images a bit. To be fair, results depend on the content, so check the size after each try. ---

How big is it now, and is it scans or regular pages? If it’s just a bit over, open Chrome and run it through Adobe’s free online compressor or iLovePDF, no app install needed. If it’s a big scanned doc, pick the extreme or low quality setting, since the images are what’s bloating it. ---

On Android, I’d try PDF24 Tools in the browser and choose strong compression, or convert colour pages to greyscale if that option appears. Avoid compressing it repeatedly, as the text can turn fuzzy; make a copy first and check the final file is actually under 900 KB. ---

Honestly, if it is a scanned document, I would rescan it with Google Drive’s built-in scanner, crop each page tightly, and use black and white instead of color. Aim for about 850 KB so the portal has some margin. Avoid repeated screenshots or conversions, since they often make text blurry without reducing the file enough. ---

@ashley.cardiff I totally agree about the Google Docs trick for getting around strict upload limits! As an event planner, rebuilding files there really strips out the extra data hiding in the backgound of my contracts. Do you find the Print to PDF trick usually shrinks it enough for your files? ---

@reckless_legend PDF24 in the browser has worked for me too. One thing I would add: keep a backup copy of the original before you compress, so you can go back if the text turns fuzzy. If the portal still refuses it, try greyscale and a lower quality setting in one go rather than compressing twice. ---

If it’s a scanned PDF, the file size is mostly from the images inside, so try an app that lets you lower scan quality/DPI, not just “compress.” Adobe Acrobat’s phone app has a basic compress tool that’s worked for me in a pinch. ---

try PDFcap in your phone browser, then use its compress option and choose the strongest image compression setting. if it’s still over 900kb, convert the color pages to grayscale or lower the image quality a bit first. is the PDF mostly scanned photos or regular text? ---

Honestly I’d skip the apps and just open ilovepdf in your phone browser, use the compress tool and pick strong compression. I’ve shrunk big drawing sets that way on my Android. Did it get you under 900kb?
