How to compress images for web uploads
Large images slow down pages and can fail on upload forms. Compression reduces file size by saving the image with more efficient settings. The goal is not to make the smallest possible file; it is to make a file that is light enough and still clear.
Compression vs resizing
Compression changes how the image is saved. Resizing changes pixel dimensions. If the photo is 4000 pixels wide but only needs to appear in a small page area, resize first. If the dimensions are fine but the file is still heavy, compress it.
Good starting points
- Blog photos: resize to the displayed width, then use JPG around 75-85% quality.
- Form uploads: follow the size limit first, then check readability.
- Screenshots: PNG may be sharper, but JPG can be smaller for photo-like images.
- Product or portfolio images: avoid compression so heavy that edges and text look damaged.
Check the result
Always preview the compressed image. Look at text, faces, edges, and gradients. If they look rough, raise the quality or use a larger image size.
한국어 요약
웹 업로드용 이미지는 너무 작게 만드는 것보다 “충분히 가볍고 읽기 좋은 상태”가 중요합니다. 사진은 JPG 품질 75-85% 정도부터 확인하고, 크기가 너무 크면 압축 전에 리사이즈를 먼저 하세요.
