Compress PDF to 500KB — frequently asked questions

Is 500 KB better than 100 or 200 KB?+

It gives the compressor more headroom, so images generally come out sharper. Use it whenever the form's limit allows it.

Will my file actually reach exactly 500 KB?+

It aims for under 500 KB, not exactly 500 KB — the result is usually a bit smaller than the limit.

Adakah anda memuat naik fail saya ke pelayan?+

Tidak — setiap alat di sini memproses fail anda sepenuhnya pada peranti anda, dan tiada apa dimuat naik ke pelayan. Satu-satunya pengecualian ialah alat AI, yang menghantar teks yang diekstrak (bukan fail) ke Claude untuk melakukan kerjanya.

Adakah terdapat had saiz fail?+

Kami tidak mengenakan had buatan, tetapi kerana pemprosesan berlaku dalam pelayar anda, fail yang sangat besar (500+ MB atau 1,000+ muka surat) dihadkan oleh memori peranti anda, bukan oleh kami.
