Compress PDF to 100KB — frequently asked questions

Will 100 KB always be possible?+

Not always. A short, mostly-text PDF gets there easily. A long, image-heavy or scanned document may not fit without unreadable quality loss — the tool tells you honestly if it couldn't hit the target.

Will the text still be readable?+

Yes — text stays selectable and sharp far longer than images do, since the compression works by re-rendering and shrinking page images, not by degrading text.

Why 100 KB specifically?+

It's a common hard limit on government portals, exam boards, and some job application forms. If your form allows more, try Compress PDF to 500 KB or 1 MB for a better-looking result.

Apakah file saya diunggah ke server?+

Tidak — setiap alat di sini memproses file Anda sepenuhnya di perangkat Anda, dan tidak ada yang diunggah ke server. Satu-satunya pengecualian adalah alat AI, yang mengirim teks yang diekstrak (bukan file) ke Claude untuk melakukan tugasnya.

Apakah ada batas ukuran file?+

Kami tidak menerapkan batas buatan, tetapi karena pemrosesan terjadi di browser Anda, file yang sangat besar (500+ MB atau 1.000+ halaman) dibatasi oleh memori perangkat Anda, bukan oleh kami.
