PDF sen límite de tamaño de ficheiro
Os teus ficheiros nunca saen do teu dispositivo. Todo o procesamento realízase localmente no teu navegador.
💡 Scanned or image-heavy PDFs shrink the most with the image options. Text-only PDFs are usually already small — if nothing helps, we’ll tell you the file is already optimized rather than hand you a bigger one.
Email PDF tips
Most email providers cap attachments at 10–25 MB. Compress PDFs to under 5 MB to ensure reliable delivery.
A 20 MB PDF can take 30+ seconds to download on mobile. Compressing to 2 MB cuts that to 3 seconds.
Compression happens entirely in your browser. Sensitive documents never leave your device.
Adjust the compression slider — start balanced and go smaller if the attachment still bounces.
