How to compress an image to any size
FAQ
Is my image uploaded to a server?
No. Compression happens locally in your browser with Canvas. Your photos are not uploaded, stored or sent through a queue. You can compress to any KB or MB size without an internet connection after the page loads.
Which formats are supported?
JPG, PNG and WebP are supported up to 100MB per file. For tough size limits like any KB or MB size, PNG may be converted to a smaller photo-friendly format to meet the target.
Will the quality drop when compressing to any KB or MB size?
KBPress searches for the best quality setting first. If any KB or MB size is extremely small for your image, it gradually reduces dimensions so the file can actually fit. For most photos at any KB or MB size, quality loss is barely noticeable.
Do I need to sign up or create an account?
No. KBPress has no sign-up, no login, and no account system. Open the page, compress your image, download it, and leave. No email, no password, no trial period that expires.
Can I compress to any KB size, not just presets?
Yes. The custom workbench lets you type any KB or MB target. KBPress will find the best quality and dimension settings to hit that size.
What is the difference between KB and MB compression?
1 MB = 1024 KB. Use KB targets (like 50KB or 100KB) for form uploads and strict limits. Use MB targets (like 1MB or 2MB) for email attachments and sharing.
