500KB is a common ceiling for resumes and cover letters on job-application systems and school or college application portals. At this size, a multi-page resume plus a cover letter usually compresses comfortably at the Recommended preset, well short of Extreme.
Compress a PDF nowHalf a megabyte is a relatively generous budget for text-based documents like resumes, cover letters, and short application essays, since those files are naturally small before compression even starts — the size usually comes from a headshot photo, a styled template with background graphics, or an embedded logo. Recommended-quality compression typically handles that combination without visibly degrading how the document looks to a recruiter or admissions reader.
A resume or cover-letter PDF that is unexpectedly large is often carrying a high-resolution photo, a decorative background image, or an embedded font set — these are exactly what compression targets.
Add the file in your browser; there is no account or upload to a server required for the compression itself.
Recommended balances size and visual quality well for text-heavy, professionally formatted documents like resumes — Extreme is rarely necessary at this size target.
Open the compressed file to confirm your layout, fonts, and any photo still look sharp before attaching it to an application.
No — compression targets images and embedded graphics, not text. A resume’s actual text stays sharp at any preset; only a photo or decorative background image loses some quality under stronger compression.
It is almost never the text itself — a headshot photo, a template with a background image or graphic header, or embedded custom fonts are the usual culprits, and Compress PDF can shrink those without touching the wording.
If they are two separate PDF files, compress each one individually; if you have merged them into a single document, compress the combined file so the whole submission clears the application portal’s limit.
