Compress PDF Too Large to Email: Reduce Below 25 MB in One Step

Reduce a PDF too large to email below the 25 MB limit. Free, no signup, no watermark. Files up to 50 MB, deleted after one hour.

    Runs the same engine as our Compress PDF tool.

    Your mail server rejected the attachment because it's over the size limit—often 25 MB. With GekiPDF's compress tool, you can shrink a PDF down to fit that limit in about a second per 16-page scan. Upload your file (up to 50 MB), pick a preset, and download the smaller version. No signup, no watermark, and your file is deleted after one hour.

    Choose Light (~200 DPI) if you need near-original quality but still want a reduction; Recommended (~150 DPI) usually cuts size by up to 95% while keeping text sharp; Extreme (~96-120 DPI) gets the smallest file but may soften images. The tool rewrites the PDF, drops metadata, and keeps the text layer so you can still search and select text.

    Frequently asked questions

    What if compressing doesn't get my PDF small enough?

    If the compressed file is still over your email limit, use split-pdf to break it into parts under 20 MB each. Send multiple smaller attachments instead of one large one.

    Will compressed PDFs lose text quality?

    No. The text layer stays intact because Ghostscript re-renders pages at lower DPI but preserves vector text. Only bitmap images are downsized, so paragraphs remain crisp for reading.

    How fast is compression for a typical document?

    A 16-page scanned PDF takes about 1 second to process. Larger files may take longer, but you get up to 40 conversions per hour per IP address.
