Comprimi PDF
Dicci il limite di dimensione richiesto dal tuo portale — NSP, CUET, DU CSAS, JOSAA, o un tuo numero esatto — e porteremo il tuo file al di sotto.
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.
Perché una "dimensione target" invece di un semplice cursore?
La maggior parte degli strumenti di compressione ti chiede di indovinare un livello di qualità sperando che il risultato vada bene. Se hai un limite preciso — un portale per borse di studio, un modulo di ammissione, il caricamento per un esame — dirci direttamente il numero è più veloce e risolve davvero il tuo problema.
E se non riesce a raggiungere il mio obiettivo?
I PDF scansionati o ricchi di foto si comprimono molto. I PDF di solo testo sono già efficienti e hanno un limite minimo — ci avvicineremo il più possibile e te lo diremo onestamente, invece di fingere che abbia funzionato.
Il mio PDF viene caricato per comprimerlo?
No — la compressione avviene interamente nel tuo browser usando WebAssembly. Il tuo file non lascia mai il tuo dispositivo né tocca un server.
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.
