2. Hold Ctrl and right-clickFlecto opens the blue edit dial. Choose Reduce size, then Target size.
3. Type the limitEnter the limit in MB, for example 9 in the size box, or drag the slider. Flecto shows the original size above it.

Good to know

• Flecto first rewrites the PDF without touching how it looks. Only if that is not enough does it offer image-only pages, which removes selectable text and links, and only when you allow it.
• Aim a little below the limit. Attachments grow slightly when they are encoded for sending, so a 9 MB target is a safe choice for a 10 MB limit.
• In a hurry? The same menu has Keep quality, Smaller and Smallest, each showing its size before you choose.
• The free plan includes 10 conversions every week. Failed or cancelled files do not count.

How big can an email attachment be?

These limits apply to the whole message, so two attachments share them. They are set by the mail provider and can change, so check when a message bounces. The recipient’s server has its own limit too, and a message that leaves your outbox can still be refused on arrival.

Why not use an online PDF compressor?

The PDFs people email are often the ones that should not be uploaded to a stranger’s server: contracts, payslips, ID scans, medical letters. Flecto does the work on your own PC, shows you the size before it saves, and leaves the original file exactly as it was.
