Frequently asked questions
How do I get my photo under 100 KB?+
Just drop it here. The tool repeatedly re-compresses at decreasing quality (and downscales as a last resort) until the result is at or below 100 KB, then shows you the final size.
Will the photo still look acceptable?+
Yes — it keeps the best quality that fits the limit, rather than crushing the image blindly. For strict limits like 100 KB on large photos it may reduce dimensions slightly, which is normal for upload forms.
Is my image uploaded anywhere?+
No. All compression runs locally in your browser, so even ID photos and documents stay completely private.
Why does the quality percentage vary between images?+
Each photo compresses differently depending on detail and colours. The tool picks the quality each image needs to meet the same target size, so the percentage shown can differ file to file.
