Large photos slow down websites, fill up phone storage and get rejected by upload forms. Compressing them can cut the size by 60–90% with no difference you can see on screen.
How to compress an image
- Open Compress Image.
- Upload one or more JPG, PNG or WEBP files.
- Choose a quality level, or type a target size in KB.
- Compare before and after, then download.
Choosing the right settings
- Quality 70–80% is the sweet spot for photos: much smaller, still sharp.
- Target size is best when a form has a strict limit like 200 KB.
- Resize first: a 4000-pixel-wide camera photo is far bigger than most screens need. Use Resize Image to 1200–1600 px for web use.
Which format is smallest?
For photos, WEBP is usually smallest, then JPG. PNG is best for screenshots and graphics with text. Convert with JPG to WEBP for websites.
Very strict limits (20–50 KB)
Government and university portals often ask for tiny files. Compress Photo to KB resizes and compresses automatically until the photo fits.
Conclusion
Resize to the size you need, compress at around 75% quality, and pick the right format. Your images will load faster and upload without errors.
