Compress images online without uploading
This free image compressor can reduce a photo or graphic for a website, email, form, or social post. Set a maximum width and choose the output format that fits the job.
What happens to the original image?
Your original file is never overwritten. PicoBento creates a new browser-side output and gives you a download link.
Can I compress PNG transparency?
Yes. Keep PNG as the output format when you need transparency. WebP can also preserve transparency in modern browsers.
