Try our PDF Tools for Android to compress PDF files offline.
Set image quality first. Image quality value can be 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). You can close "Settings" section by clicking the "X" on the right if you use default settings.
Drag multiple PDF files to the "Add Files" section. Each PDF file size can be up to 40m.
The compressing automatically starts when files are uploaded. Please be patient while files are uploading or compressing.
The output files will be listed in the "Conversion Results" section. To compress all output files in a ZIP file, click "" icon on the right, then click "Add to ZIP". You can right-click on file name and click "Save link as..." to save the file. The output files will be automatically deleted on our server in two hours, so please download it to your computer or save it to online storage services such as Google Drive or Dropbox as soon as possible.
Sometimes output file size may not be reduced after compression, this is because the file may be compressed before or has lower quality than settings. For example, changing a PDF file's image quality to 60 will not reduce size of PDF file which original image quality is below 60. If this happens, try entering a smaller image quality value such as 20.
