Best PDF compressor for students

Why students need a PDF compressor

The PDF compressor tools students use most

• •Compress PDF: Compressing a PDF reduces file size — often 50–90% on image-heavy scans — by down-sampling images and stripping redundant data, while keeping text selectable.
• •Flatten PDF: Flattening a PDF merges form fields, annotations and layers into the page, so nobody can change filled-in values and the file renders everywhere.
• •Repair PDF: Repairing a PDF rebuilds a damaged file's internal structure, recovering as much readable content as possible from a document that won't open.
• •Grayscale PDF: Converting a PDF to grayscale removes colour from every page, which cuts file size and prepares a document for black-and-white printing.
• •Resize PDF: Resizing a PDF changes the page dimensions — for example scaling to A4 or Letter — so a document prints and fits the way you need.
• •Multiple Pages per Sheet: N-up layout places two, four or more PDF pages onto a single sheet, so you can print handouts and save paper.
