PDF Compressor: Reduce Size by Inkmal Solution
Updated 5 November 2026
Your documents
PDF compression and previews run on your phone. We do not upload your PDFs to our servers. Original documents are not overwritten. Compressed copies are saved in the app Library until you remove them or uninstall the app. Export a copy if you want to keep it outside the app.
Before and after comparison
The app stores the original document location and a file fingerprint locally so you can compare it with the saved result. A temporary original copy is used while comparing and removed when you close the comparison. Interrupted comparison copies are cleaned when PDF processing next starts in a fresh app process. Another permanent copy of the original is not added to your Library. If the original is moved or unavailable, you can choose it again.
Finding files
You choose documents and folders through Android's file picker. The app stores a local index of names, sizes and document locations for connected folders so you can search them. It does not receive unrestricted access to all files on your phone. Cloud providers you choose may download files using their own services.
Sharing and exports
Documents are shared or exported only when you choose these actions. The destination app or storage provider handles the copy under its own privacy policy.
Advertising
The app integrates Google Mobile Ads. Google may process device identifiers, approximate location inferred from IP address, ad interactions and diagnostic information to deliver, measure and protect advertising. Ad personalisation depends on your consent, device settings and applicable regional requirements. Where required, Google's consent form and privacy options are available in the app. Optional rewarded ads grant two ad-free compression batches after Google confirms the reward. The remaining reward balance is stored locally on your phone.
Your choices
You can remove saved copies in Library, clear this app's data through Android settings, or uninstall it to delete its local data. Exported and shared copies must be removed from their destination separately. Android settings let you manage the advertising ID.
Children
This app is intended for people aged 13 and above and is not directed to children under 13.
