Compress an image to 100KB

Why use this converter
- Enough for full-width content images
Comfortable for the widths a typical article column uses.
- Keeps long posts light
Ten images at 100KB is a page that still loads quickly.
- Safe for email
Newsletters stay well within the weight most clients handle gracefully.
- Pre-set and ready
The target is already 100KB when the page opens.
When to use it
- Blog and article body images: Looked at properly, so worth more than a thumbnail budget.
- Email newsletter images: Total message weight matters; several images add up quickly.
- Documentation screenshots: Text in the image needs to stay readable.
- Social preview images: Shown at moderate size across a range of platforms.
Screenshots need more care than photographs
A screenshot containing interface text is much harder to compress than a photograph. JPEG smears the sharp edges that letterforms depend on, and the result is text that looks slightly fuzzy without it being obvious why.
If the screenshot is mostly text or interface, keep it wider rather than pushing the file size down aggressively, and crop tightly to the part that matters. Cropping is free quality: the pixels you remove cost nothing, unlike the ones you degrade.
Why the tenth image matters more than the first
Readers rarely abandon a page over one heavy image near the top. What loses them is a long article that keeps stalling as they scroll, because every image below the fold is still full weight.
Keeping each image around 100KB means a twenty-image post stays around 2MB rather than 10MB, and the scroll stays smooth the whole way down. Lazy loading helps too, but it delays the cost rather than removing it.
Frequently asked questions
Is 100KB enough for a full-width blog image?
For the widths most content columns use, yes. A full-bleed image spanning a large screen benefits from a larger target.
My screenshot text looks fuzzy — why?
JPEG compression struggles with the sharp edges in text. Crop tightly and avoid pushing the size down hard; for heavy text, a larger target is worth it.
Is this small enough for a newsletter?
Yes. Several images at this size keep a newsletter well within what mail clients handle comfortably.
Can I compress several at once?
Yes, and each is compressed towards the same target.
