Why 1MB Is the Magic Number for PDFs
1MB is the most widespread PDF size limit on the internet. Email providers may allow 25MB attachments, but corporate mail gateways, ticketing systems, CMS media libraries, and application portals routinely draw the line at 1MB per document — and reject anything over it without much explanation.
Most PDFs that violate the limit do so because of images. A single unoptimized phone photo embedded in a document adds 2–5MB by itself; slide decks exported to PDF carry full-resolution graphics on every page. Recompressing those embedded images is where the dramatic size reductions come from, which is exactly what this tool automates.
There's a speed bonus to going local: a 20MB PDF needs no upload time at all. Compression begins the instant you drop the file, making this the fastest route from oversized attachment to sendable email.
