Compress Image to 100KB – Questions & Answers

Can a 5MB smartphone photo really be compressed to 100KB with good quality?
Yes. Standard smartphone cameras capture photos with redundant metadata and excessive uncompressed pixel density. By optimizing the quantization matrix and discarding unnecessary metadata, our engine retains high visual fidelity under 100KB.
Is there a limit on how many images I can compress to 100KB?
No limits. You can compress as many photos as you want, completely free of charge.
How does this compare to server-based compressors like TinyPNG?
Unlike server-based tools that send your photos to remote cloud servers, our tool processes everything locally on your computer or phone using the Canvas API, providing instant results and complete privacy.
Can I also set custom pixel dimensions while compressing to 100KB?
Yes! Toggle the dimension fields to set exact width and height (e.g. 1080x1080 or 800x600) alongside your 100KB file size target.
