How to compress images without making them look blurry
Reduce image file size by choosing dimensions, format, and quality in the right order.
Quick answer
Resize oversized pixel dimensions before lowering quality. For photos, WebP or JPEG usually saves more space than PNG; for diagrams and transparency, PNG or WebP may preserve edges better.
Step by step
Keep the original, set the longest side to the actual display need, choose the output format, and start with balanced quality. Compare faces, small text, gradients, and edges at 100% before downloading.
Common mistakes
Repeatedly recompressing a JPEG compounds damage. Raising quality cannot restore lost detail, and converting a photograph to PNG often makes the file larger without improving the source.
Completion check
Check the output dimensions, file size, transparency, orientation, and the areas users care about. Keep the smallest version that still passes the visual check.
