Source Complexity
Fine detail and noise can require more compression.

Compress an image to 200KB or less with a preset limit. Compare the generated file against the original and keep control of quality, dimensions and format.

The editor calculates settings from the source instead of applying one fixed quality to every image.
Fine detail and noise can require more compression.
Large dimensions can make the target harder to reach at high quality.
JPEG, WebP and AVIF each support the target calculation.
Quality is searched first; proportional resizing is the fallback when the file remains above 200KB.
Open the editor and confirm the target reads 200 kB.
Inspect the generated quality and dimensions against the source.
Use the actual output size to confirm the requirement was met.
The editor keeps the generated format, quality and resize settings after calculating the active image.
Apply the calculated quality to another image when appropriate.
Keep the generated resize settings for sources with a compatible aspect ratio.
Another source can produce a different file size with the same settings.
Calculate a 200KB result and compare quality, size and dimensions.
Add the image, run the preselected 200KB target, inspect the generated result, and download it when the reported size meets your requirement.
No. Vicoco treats 200KB as an upper limit and can return a smaller file.
No. Resizing is used only when quality adjustment cannot meet the limit and resize fallback is enabled.
JPEG, WebP and AVIF support the automatic target-size calculation.
Yes. When enabled, resize fallback reduces width and height proportionally.
Different sources compress differently, so one may meet the limit at full dimensions while another requires resizing.
No. Processing stays in the browser.
