Compression is not the same as resizing
Compression changes how image data is stored. Resizing changes the actual pixel dimensions. If your image is enormous, resizing may reduce file size more cleanly than heavy compression.
Try Reduce Image Size for Website or Compress Image for Upload depending on the problem.
Start with the right format
Photos are usually smaller as JPG or WEBP. Screenshots and graphics are often cleaner as PNG. If file size matters most, WEBP is often worth testing.
Useful converters: PNG to JPG, JPG to WEBP, PNG to WEBP, and WEBP to JPG.
Compress for email
Email services often reject large attachments or make them annoying to send. Use a target-size tool when you need something predictable.
Use Compress Image for Email, Compress Image to 100KB, or Compress Image to 200KB.
Compress for upload forms
Job applications, school portals, passport forms, and government-style upload forms often have strict file limits. These pages usually care more about size than perfect visual quality.
Use Compress Image for Upload or Compress Image Under 1MB.
Compress for websites
Website images should be as small as possible while still looking clean. Large images slow down pages and waste bandwidth.
Use Reduce Image Size for Website, JPG to WEBP, or PNG to WEBP.
When PNG files are too big
PNG is great for sharp graphics, but photos saved as PNG can become massive. If transparency is not needed, convert the file to JPG or WEBP.
Try PNG to JPG or PNG to WEBP.
Avoid over-compressing important images
If text becomes blurry, faces become smeared, or edges look blocky, your file is probably compressed too hard. Use the largest file size that the upload limit allows.
For cleaner results, use Reduce Image Size Without Losing Quality.
