Comprimir PDF
Dinos el límite de tamaño que realmente pide tu portal — NSP, CUET, DU CSAS, JOSAA, o tu propio número exacto — y haremos que tu archivo quede por debajo.
Cómo funciona
Sube tu PDF, escribe un tamaño objetivo exacto (o elige compresión baja, recomendada o extrema) y descarga — todo ocurre en tu navegador usando WebAssembly, así que tu archivo nunca toca un servidor.
¿Por qué "tamaño objetivo" en lugar de un simple control deslizante?
La mayoría de las herramientas de compresión te piden que adivines un nivel de calidad y esperes que el resultado encaje. Si tienes un límite exacto — un portal de becas, un formulario de admisión, la subida de un examen — decirnos el número directamente es más rápido y realmente resuelve tu problema.
¿Y si no puede alcanzar mi objetivo?
Los PDF escaneados o con muchas fotos se comprimen mucho. Los PDF de solo texto ya son eficientes y tienen un límite mínimo — nos acercaremos todo lo posible y te lo diremos con honestidad, en lugar de fingir que funcionó.
¿Se sube mi PDF a un servidor para comprimirlo?
No — la compresión ocurre por completo en tu navegador usando WebAssembly. Tu archivo nunca sale de tu dispositivo ni toca un servidor.
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.
