How can I email a batch of project photos to a client without Gmail or Outlook refusing the size?
Compress all the photos in one batch, read the Total line under the table, lower the quality until that total sits comfortably below your mail provider's limit, and attach the ZIP the tool gives you. What counts is the sum of the photos, not each one, because mail providers cap the size of the whole message, and that cap differs from one provider to another.
The cap is on the message, not the photo
When your email bounces for size, it is usually because the attachments together went over the limit for a single message. Twenty photos that each look reasonable can add up to too much. The limit also differs between Gmail, Outlook and your client's company mail, and it can change over time, so check the current figure on your provider's help page instead of relying on a number you heard. Keep in mind the recipient's mailbox may accept less than yours sends.
One more technical detail: attachments are converted to text for sending, which inflates them by roughly a third. Some providers apply their limit after that growth, so leave a comfortable margin rather than aiming right at the cap.
Example: twenty project photos
One 1600×1200 photo of 689.5 KB came out at 250.9 KB as JPEG at quality 80 in Chrome.
If all twenty photos were similar, the total would drop from about 13.5 MB to about 4.9 MB, 63.6% smaller.
Your own photos will give different figures, and the tool's Total line shows the real sum for your batch.
Step by step
- Open the Image compressor and add all the project photos, up to 30 at a time.
- Choose JPEG, since it opens for any client on any device without surprises.
- Start at quality 80 and read the Total line. If it is over the limit, lower the quality and read it again.
- Press Download all to get a single ZIP, and rename it after the project before attaching it.
- Attach and send, and mention the number of photos in the message so the client can check they all arrived.
When a ZIP is not the right fit
- If the client will review the photos on a phone, opening a ZIP can be a nuisance. Put the photos into one PDF with Images to PDF so they can flip through page by page.
- If the photos still will not fit in one message after compressing, split them across two emails and label each file clearly, such as Part 1 and Part 2.
- If the client needs full quality for printing, compression is not the answer. Some mail providers offer to send a cloud storage link instead of an attachment, which suits that case better.
Common questions
Does zipping the photos make them much smaller?
Not noticeably. JPEG and WebP files are already compressed; the value of the ZIP is bundling them into one attachment.
Are the project photos uploaded anywhere while compressing?
No, compression runs in your browser, and the photos leave your device only when you send them.
Do the photo dimensions change?
No, compression keeps the dimensions. For much smaller files, reduce the dimensions first.
