"Image size" means two things: file size (KB/MB on disk) and dimensions (pixels). To make a photo smaller in KB, you have two levers — lower the compression quality, or shrink the pixel dimensions. A 4000px-wide photo displayed at 800px on a webpage is pure waste; resizing it first can cut 90% of the file before you even touch quality.
Start with quality compression (fast, keeps dimensions), and if the file is still too big, reduce dimensions too. Both run locally in your browser with faymox — no uploads, no waiting in a server queue.
Reduce image size in 3 steps
- Open the Image Compressor and drop your images in.
- Lower the quality slider to around 75-80 and check the resulting size.
- Still too big? Open the Image Resizer, set a smaller width (e.g. 1600px for web use), then download.
FAQ
How do I reduce photo size without losing quality?
You can't shrink bytes for free, but at quality 85+ the loss is invisible to the eye. Resizing oversized dimensions is the other "free" win — pixels nobody ever sees cost bytes for nothing.
How do I make a picture small enough for email?
Most email caps sit around 20-25 MB total. Compressing phone photos to quality 75 usually brings each under 500 KB — dozens fit in a single email.
What's the difference between resizing and compressing?
Resizing changes pixel dimensions (4000px down to 1600px). Compressing re-encodes the same pixels more aggressively. Use both together for maximum shrinkage.
