When the Source Is Already Small

Highest Tested Quality
The target search keeps the highest tested quality under the limit.
No Artificial Padding
Extra bytes are not added merely to approach 500KB.

FAQs
How do I compress an image to 500KB?
Add the image, keep the 500KB target, run the calculation, and download after checking the actual file size.
Will a 500KB result be exactly 500KB?
No. The setting is a maximum, so the result can be smaller.
Does Vicoco lower dimensions automatically?
Only when the target cannot be reached through quality adjustment and resize fallback is enabled.
Can I compress JPG, PNG, WebP or AVIF input?
You can add browser-readable images and choose JPEG, WebP or AVIF output for the automatic target.
Which format creates the best 500KB image?
There is no universal winner. Compare the actual source and choose the result that fits your compatibility and quality needs.
Can I apply the settings to several images?
Yes, but reused settings do not guarantee that every source will be under 500KB because image content differs.
Are files uploaded during compression?
No. Processing is local to the browser.
