E-Mail-Komprimierer

Everyone knows that one error message: you attach a few photos or a PDF, hit send, and the provider blocks it because the attachment is too large. The limits differ by service, but they are always in the way when you do not have them memorised. Compress for Email takes the guesswork out: pick your provider, load your files, and the tool squeezes them down far enough to fit.

The provider limits are built in. Gmail lets 25 MB through, T-Online even 32 MB, Posteo 50 MB, while Outlook, GMX and Web.de cap out at 20 MB. Just choose your service and the compressor sets the right target. Need a different value, say because the recipient's mailbox has a stricter limit, you set a custom limit.

It compresses the usual suspects: images and PDFs, exactly what blows up attachments. Phone photos today are often several megabytes each, and three or four of them break any limit. The tool reduces the file size without making the image unusable, and shows you before and after how much it achieved.

For each file you get honest feedback. If it is already under the limit, the tool tells you and leaves it alone. If it is still too large afterwards, you get a concrete hint on what to do - such as shrinking the image further or splitting it across several emails. No blind squeezing, but a clear message you can follow.

Several files can be bundled into a ZIP archive on request. That has two upsides: an archive is often smaller than the sum of the individual files, and you attach one clean file instead of a dozen. Especially when you have to send a set of receipts or photos, that is the more convenient route.

The compression runs in the browser and your files are not loaded onto anyone else's server. That makes it fast, free and data-frugal - your holiday photos or your receipts are nobody's business but the recipient you send them to.
