Many users confuse these two terms. Resizing changes the actual pixel dimensions of an image (e.g., from 4000x3000 to 1920x1080), which makes the image physically smaller on screen. Compression reduces the file size (KB/MB) without changing the dimensions. Our tools allow you to do both effectively.
Platforms like Instagram and Facebook compress uploaded images aggressively. If you upload a huge 20MP photo, their algorithms will crush it, resulting in a blurry post. The best practice is to pre-resize your images to the platform's recommended width (e.g., 1080px for Instagram) to maintain maximum sharpness.
Our tools offer flexible modes. Use Pixels when you need exact dimensions (like a website banner). Use Percentage to quickly reduce file size by scaling down (e.g., 50%). Use Aspect Ratio locking to ensure your photos don't look stretched or squashed.
Simply upload unlimited photos to our **Bulk Image Resizer**, set your desired dimensions or percentage, and process them all instantly.
