Mampatkan PDF
Beritahu kami had saiz yang sebenarnya dikehendaki oleh portal anda — NSP, CUET, DU CSAS, JOSAA, atau angka tepat anda sendiri — dan kami akan mampatkan fail anda supaya berada di bawah had itu.
How it works
1. Upload your PDF. 2. Type an exact target size in KB or MB, or pick Low, Recommended, or Extreme compression. 3. Click Compress. 4. Download the result — everything runs in your browser using WebAssembly, so your file never touches a server.
Kenapa "saiz sasaran" dan bukan sekadar penggelangsar?
Kebanyakan alat mampatan meminta anda meneka tahap kualiti dan berharap hasilnya sesuai. Jika anda mempunyai had yang tepat — portal biasiswa, borang kemasukan, muat naik peperiksaan — memberitahu kami angka sebenar adalah lebih pantas dan benar-benar menyelesaikan masalah anda.
Bagaimana jika ia tidak dapat mencapai sasaran saya?
PDF yang diimbas atau penuh dengan foto boleh dimampatkan dengan banyak. PDF teks sahaja sudah pun cekap dan mempunyai had minimum — kami akan cuba sedekat mungkin dengan sasaran anda dan memberitahu anda hasil sebenar, bukannya berpura-pura berjaya.
Adakah PDF saya dimuat naik untuk dimampatkan?
Tidak — pemampatan berlaku sepenuhnya dalam pelayar anda menggunakan WebAssembly. Fail anda tidak sesekali meninggalkan peranti anda atau menyentuh pelayan.
Does compressing a PDF reduce text quality or make it blurry?
No — compression rasterizes every page into an image, so selectable/searchable text is lost in the process rather than preserved. Scanned or photo-heavy pages look about the same since they were already images. Text-heavy pages get a higher quality floor so the text doesn't turn to mush, but they're still flattened — if you need to keep your text selectable, don't compress that file.
Can I compress a PDF that's already password-protected?
Not directly — remove the password first with a PDF reader that supports it, compress the file, then re-apply protection if you still need it.
What size does your portal actually want?
page.compress.portalTableText
Why portals reject an oversized PDF
page.compress.rejectText
Will I still be able to select or copy the text after compressing?
No. Hitting an exact byte count means every page gets rasterized to an image and re-encoded as JPEG — that's true for a scanned PDF and a text PDF alike. The result looks and prints fine, but the text is pixels, not characters, afterward. If you need the text layer to survive, compress a copy and keep your original.
Does compressing change my page count or delete anything?
No — every page you started with comes out the other side, same order, same count. Compression changes how each page is encoded, not how many there are.
Will links, form fields, or e-signatures survive compression?
No. Compression works by rendering every page to an image and rebuilding the PDF from those images, so anything that isn't visible ink — a hyperlink, a fillable form field, a digital signature object — doesn't come along for the ride. The page looks identical and a signature stamp still shows up as pixels, but the underlying interactive element is gone. If the file needs to stay fillable or the links need to stay clickable, keep your original alongside the compressed copy.
