How to Shrink Image Size Without Blur or Pixelation
The most common complaint about image compression is blur on text, soft edges on logos, and muddy detail in product photos. These artifacts aren't inevitable — they result from using the wrong format, compressing too aggressively, or resizing with a poor algorithm. This guide shows you how to compress significantly while keeping the sharpness your images need.

Match format to image type
Photos: JPG or WebP (lossy compression suits continuous-tone images). Logos, screenshots, text on solid backgrounds: PNG (lossless compression keeps sharp edges). Using JPG for a logo is the single most common cause of blurry text and edge artifacts.
Never go below 75% quality for photos with detail
For product photos, portraits, and images with fine detail, stay at 75–85% quality. Going below 70% introduces visible artifacts on faces, fabric textures, and hair.
Resize before compressing, not after
Resize to your target dimensions first, then compress. Compressing a large image and then resizing it again applies two rounds of quality loss. Always resize → compress, in that order.
Use PNG for anything with text or sharp lines
If your image has text overlay, a logo, or UI elements with hard edges, use PNG compression instead of JPG. PNG preserves all edges perfectly because it's lossless.
Check at 100% zoom, not thumbnail size
Always evaluate compressed images at 100% zoom. Thumbnails look sharp even at low quality. Open the image at full size and zoom into text, edges, and high-frequency detail to assess quality accurately.
