Compress Images Online Free — Smaller JPG, PNG & WEBP

A single photo straight off a modern phone is 4–8 MB. Put a few on a web page and it crawls; attach ten to an email and it bounces. Compression typically cuts image size by 60–80% with no visible difference at normal viewing sizes.

Compress images in 3 steps

1. Open the free Compress Image tool.
2. Drop in your JPG, PNG or WEBP files — single or batch.
3. Download the smaller versions (batches come as a ZIP).

Compression also strips hidden metadata (camera model, GPS location) — a small privacy win included free. And if a file can't be made smaller, you get your original back rather than a "compressed" file that grew.

Compression vs. resizing — which do you need?

They solve different problems and combine beautifully:

• Compression keeps the pixel dimensions and re-encodes more efficiently. Use it when the image will be viewed at full size.
• Resizing reduces the actual dimensions. A 4000px-wide photo displayed in an 800px web column is wasting 80% of its pixels — Resize Image it to 1200px, then compress, and you'll often land under 100 KB.

Common jobs

• Website images — resize to ~1200–1600px wide, then compress. Page speed is a Google ranking factor.
• Email attachments — compress a batch and stay comfortably under the 25 MB cap.
• iPhone photos — convert HEIC to JPG first, then compress.
• Documents — turning photos into a file to send? Images to PDF then Compress PDF.
