How to Compress an Image
Updated 2026-08-25
Large photos stall email, forms, and CMS uploads. Compression keeps the same dimensions while reducing bytes so files fit limits and load faster.
A2Z Edit can aim for a target kilobyte size or a quality setting, and it can handle a batch in one pass.
How to Compress an Image
- Open the Compress Image tool.
- Upload one or more images.
- Choose target file size (KB) or a quality slider.
- Run compression and review the before/after sizes.
- Download each result, or a ZIP when you compressed several files.
Why it matters
Smaller files clear attachment and upload caps without redesigning the image.
Web pages feel snappier when hero and gallery images are optimized.
Tips
- Start with a modest quality drop; bump compression only if you still miss the limit.
- Already tiny icons rarely shrink further — convert format or resize dimensions instead.
- For email, many providers behave better under a few hundred KB per image.
Frequently asked questions
Is compression lossless?
Most practical compression for web photos is lossy. You trade a little visual detail for a much smaller file.
Can I compress multiple images at once?
Yes. Add several files, compress them together, and download as a ZIP when ready.
