Image Compressor

Compress Image to 500 KB

A 500 KB ceiling is the modern web sweet-spot for hero and feature imagery.

Your images stay on your device. Nothing is uploaded.

Pages that hit Core Web Vitals targets keep individual images below 500 KB, especially for above-the-fold imagery. The compressor settings below are pre-biased for that target — adjust quality if you want to fine-tune the trade-off.

Compression is fully client-side. Drop a photo and see the resulting size before downloading.

Frequently asked questions

How do I compress an image to 500 KB?
Upload your image and the default settings on this page are pre-tuned to land you around 500 KB. Use the quality slider to nudge the file size up or down — the result preview shows the exact byte count before you download.
Will the image still look good at 500 KB?
For most photos, yes. The pre-tuned quality and max-dimension settings prioritise visual quality while landing close to 500 KB. Very small targets (under 100 KB) on detailed images may need a visible quality reduction.
Which format gives the best result for 500 KB?
WebP usually produces the smallest file at a given quality, then JPEG, then PNG. The format selector lets you switch; the default reflects the best balance for 500 KB.
Can I compress to exactly 500 KB?
Browser compression is quality-driven, not byte-driven, so the resulting file size is close to — but not exactly — 500 KB. Staying under a target is what email clients, forms, and platforms enforce, so a slightly smaller file is always safe.
Can I batch compress multiple images to 500 KB each?
Yes — use the bulk compressor. Drop a folder of images and each one is processed with the same settings, then downloaded as a ZIP.
