PDFCompress is an online PDF compressor that reduces PDF file size to make documents easier to upload, share, and store. Use it in a web browser without installing software or creating an account. Upload up to five PDF files at once, with support for files up to 1 GB each, and choose low, medium, or high compression to balance file size and visual quality. A grayscale option can further reduce the size of documents that do not need color. Compression results vary depending on the file and selected settings. PDFCompress is designed to preserve readable text, images, and document formatting while creating smaller PDF files for email attachments, online forms, reports, and other everyday uses. Files are encrypted during transfer and processing and automatically deleted within 24 hours. The service supports most standard PDFs; password-protected or encrypted files may need to be unlocked before compression.
