How to reduce image file size for email

A photo can be much larger than the version a recipient needs to view on screen. There are two separate ways to reduce its size: use fewer pixels, or store those pixels with more compression. Try one change at a time so you can see which trade-off works for your picture.

Start with a copy of the original

Keep your original photo before editing. Check the attachment limit shown by your email service; limits vary, and the whole message may need to fit, not just one attachment. If you have several photos, compare their combined size after exporting.

Reduce dimensions when the image is larger than needed

Open the image resizer, select the photo and keep original proportions enabled. For a photo intended mainly for a screen, try a width of 1600 pixels as a starting point, then inspect the result. This is a practical starting point, not a universal requirement. Small text or print use may need more detail.

Adjust JPEG quality and compare

Use the image compressor to export a JPG. Begin around 0.8 quality and compare the new file size with the original. If it is still too large, lower quality gradually. Watch for fuzzy edges, blocky detail and unreadable text. A smaller file is useful only if it still communicates what you need.

Choose a different approach for transparency or text

JPG replaces transparent areas with white and can soften sharp lettering. A PNG may be more suitable for a logo or screenshot. Read the image format guide before changing a graphic with a transparent background.

Check the downloaded file

Open the exported file, confirm its dimensions and readability, then attach that version to your message. Kalika processes your photo locally; sending it through email is a separate action you choose.
