Frequently Asked Questions
How do I reduce a photo to 100 KB?
Upload the image and click Resize — the tool automatically finds the highest JPEG quality that keeps the file at or under 100 KB. Most photos look essentially unchanged at this size.
When is a 100 KB image needed?
Document upload portals, contact forms with attachment limits, website images that need to load fast, and email systems with strict attachment quotas all commonly call for images around 100 KB.
Does compressing to 100 KB reduce the resolution?
No — by default the pixel dimensions stay the same and only the JPEG compression increases. Untick “keep original dimensions” if you also want a smaller resolution, which further improves quality per kilobyte.
