Different situations call for different PDF file sizes. Here's a guide to help you know when compression is needed and what sizes to target:
Most email providers limit attachments to 10-25MB. Gmail allows 25MB, Outlook 20MB. Compress your PDFs to fit within these limits for reliable email delivery without bouncing.
Job applications, government portals, and online forms typically limit uploads to 2-5MB. Compress resumes, tax documents, and applications to meet these strict requirements.
Save valuable cloud storage space by compressing archived PDFs. Reduce storage costs on Google Drive, Dropbox, and OneDrive by shrinking document sizes by 30-70%.
PDFs hosted on websites should be as small as possible for fast downloads. Compress brochures, catalogs, and downloadable guides for better user experience and page speed scores.
Large PDFs are slow to load on mobile devices and consume data. Compress documents that will be viewed on phones and tablets for a smoother reading experience.
When dealing with hundreds of PDF files, compression adds up. Reduce each file and save gigabytes of storage across your entire document library.
