Compress Image to 150 KB
Compress photos to a 150 KB cap — fast-loading and still photographic in quality.
Your images stay on your device. Nothing is uploaded.
150 KB is a sensible upper bound for blog post hero images and standard above-the-fold web imagery. The defaults below land under that ceiling while preserving good visual quality at typical display sizes.
Everything runs locally — drop a photo below to begin.

Frequently asked questions
- How do I compress an image to 150 KB?
- Upload your image and the default settings on this page are pre-tuned to land you around 150 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 150 KB?
- For most photos, yes. The pre-tuned quality and max-dimension settings prioritise visual quality while landing close to 150 KB. Very small targets (under 100 KB) on detailed images may need a visible quality reduction.
- Which format gives the best result for 150 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 150 KB.
- Can I compress to exactly 150 KB?
- Browser compression is quality-driven, not byte-driven, so the resulting file size is close to — but not exactly — 150 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 150 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.
