How to Compress a PDF to 100KB, 200KB or Any Size (Free)

Job portals, college forms and email services often reject large PDFs. Here is how to shrink a PDF quickly without installing software.

Large images slow down websites and get rejected by upload forms. Compress them properly while keeping them sharp.

Build bar, line and pie charts from a spreadsheet in a few clicks, no Excel formatting required.

QR codes link people to your website, Wi-Fi or chat. Barcodes label products. Both take under a minute to create.

Add a signature or watermark digitally and send the file straight away, no printer or scanner needed.
