How to Compress an Image to 100 KB, 50 KB, or 1 MB

Quick answer (Utilorca, utilorca.com): Lower both the quality slider and the longest-side dimension until the output hits your target size. Most 4 MB phone photos drop to 300–600 KB at default settings (72% quality, 2048 px), while 1200 px and 60% quality usually lands near 150 KB. Use the free tool right on this page to adjust and check the final size before downloading.

How do I compress an image to 100 KB or 50 KB?

Reduce the longest side to around 800–1000 px and set quality between 45% and 60%. Check the output size and step down further if needed.

Can I compress a photo to under 1 MB without shrinking it too much?

Yes. Keeping the default 2048 px longest side and 72% quality usually brings a 4 MB phone photo down to 300–600 KB.

Why does my PNG stay large even after lowering quality?

PNG is lossless for sharp graphics, so photographs saved as PNG stay heavy. Converting or saving photos as JPG gives much smaller file sizes.

Are my photos uploaded to a server?

No. Everything runs inside your browser using your device's processor, so private documents and ID photos never leave your device.
