3. Free Credits

Compressor.io does not mention the credits it offers for free though it has a paid version that costs a minimum of $50 per year for one user. The AI Image Compressor offers 100 credits when it comes to compressing images only. Additionally, every free user is reimbursed with credits each month so you can keep using the free version for a long time.

4. Other Editing Features Like Flipping, Cropping Images and More

Both tools do not offer much for editing features unless paid for. If you have the Pro version of Compressor.io, you can set the width and height of the image beforehand. You can also set the image quality if the image is JPG, PNG, or WEBP. Now, although Vance AI Image Compressor does not offer much, you can make use of other Vance AI tools such as the image enlarger, photo colorizer, image sharpener, and more. Overall, there are more options with Vance AI. 

Conclusion


Image compressing is essential for storage space saving and increasing load times for websites and similar pages. While both of these tools offer great results, the final decision boils down to user preferences and needs. Vance AI offers better quality with more features through other Vance AI tools whereas Compressor.io has better compatibility.
