Compress image to 100KB
Use a target size and export WebP/JPG without uploading files.
TL;DR
- Size: 100KB target (best-effort, may require downscaling).
- Ratio: keep original ratio to avoid distortion.
- Format: WebP for smallest files, JPG for compatibility.
3 steps (using this tool)
- Upload your image(s) and set Target size (KB) to 100.
- Pick WebP or JPG and adjust max width/height if needed.
- Compress and download, then verify file size.
Step-by-step
- Upload your image(s).
- Set “Target size (KB)” to 100.
- Choose WebP (recommended) or JPG.
- Click Compress, then download (or Download zip).
If it can’t reach 100KB
- Lower max width/height (downscale).
- Use WebP instead of JPG for photos.
- Reduce max quality (e.g. 80%).
FAQ
Can you guarantee exactly 100KB?
Not always. 100KB is a best-effort target—some images need downscaling or format changes to reach it cleanly.
Quick tip: If quality collapses, keep quality higher and reduce dimensions instead.
Common mistake: Forcing extremely low quality—results become blocky and unusable.
What format should I use to hit 100KB?
Try WebP first for photos; otherwise use JPG. PNG is the hardest to shrink under 100KB.
Quick tip: If a platform doesn’t accept WebP, export JPG and downscale slightly.
Common mistake: Trying to hit 100KB with PNG screenshots—lossless files resist shrinking.
What should I change first: quality or dimensions?
Lower quality first for photos; if still too big, downscale dimensions for a major reduction.
Quick tip: Small downscales often save more than big quality drops.
Common mistake: Keeping huge dimensions and lowering quality too far—poor clarity with limited gains.
How do I keep text sharp under 100KB?
Use high contrast, larger fonts, and avoid ultra-low quality settings.
Quick tip: Prefer slightly smaller dimensions over aggressive compression.
Common mistake: Using tiny fonts—compression makes thin strokes disappear.
Do you upload my images?
No. Processing happens locally in your browser. Your files are not uploaded.
What size should I use?
Use the recommended size.
Which export format should I use?
JPG for photos, PNG for text/logos or transparency, WebP for smaller files (if supported).
Crop vs Pad — what is the difference?
Crop fills the target size (may cut edges). Pad fits the whole image and adds background/space.
How do I protect text and logos?
Keep important content centered and avoid placing critical text at the edges.
Can I batch resize?
Yes. Use the Batch Resizer to apply the same size to many images.
