Compress JPG to 100KB or Less
The preset starts with JPEG output for the common JPG-to-100KB task, while WebP and AVIF remain available.
100KB Maximum
The result can be smaller than 100KB; it is not padded to an exact size.
Highest Tested Quality
Vicoco searches for the highest tested quality that stays under the limit.
Optional Resize
Proportional resizing is used only when enabled and quality is not enough.
Control the 100KB Result
Compare the encoded image, actual file size and output dimensions instead of relying on the quality number alone.
Quality search
The highest tested quality under the limit is retained.
Resize fallback
Dimensions can change when quality alone is insufficient.
Three Steps to a 100KB Image
- 01
Add a JPG or Image
Choose a source image, folder, dropped file or clipboard image.
- 02
Run the 100KB Target
Use the preselected maximum and let the editor calculate quality and optional resizing.
- 03
Verify the File
Check actual size, visual detail and dimensions before download.
Verify the Generated File
Image content and dimensions mean the same quality can create different file sizes.
- File-Size Readout
- Confirm the generated output is within the 100KB maximum.
- Format and Quality
- Review the selected encoder and calculated quality.
- Resize Status
- Check whether the fallback reduced image dimensions.

FAQs
How do I compress a JPG file to 100KB?
Add the JPG, keep the 100KB target, let Vicoco test the output, and download after confirming the reported size.
Will the JPG be exactly 100KB?
No. The target is a maximum, so the file can be smaller than 100KB.
Does the tool preserve the original dimensions?
It preserves dimensions when quality adjustment is enough. If resize fallback is needed, the result reports the reduced width and height.
Can I use WebP or AVIF for a 100KB result?
Yes. The target-size control supports JPEG, WebP and AVIF output.
Why do two images need different quality settings?
Image detail, noise, colours and dimensions affect compressed size, so each source can require a different quality.
Can I process a folder after testing one image?
Yes. Review the active image first, then use its resulting settings for the queue. Queue files are not guaranteed to have identical sizes.
Does Vicoco upload the JPG?
No. Processing runs locally in the browser.
