When 1MB is the right target
1MB is a relaxed limit. Most services accept it without complaint, and for many purposes a 1MB image is visually identical to the original. If you are dealing with high-resolution photos, product images, or any content where detail matters, 1MB is often the smallest size that still preserves everything.
At 1MB, you essentially never need to touch dimensions. The encoder has enough budget to keep the full resolution of a 20-megapixel photo intact while landing comfortably under 1MB with JPG quality 90-95. The result looks identical to the original at any screen size, including large desktop monitors.
What 1MB allows
Common uses of the 1MB target:
- High-quality product photos for marketplaces
- Portfolio images on design and photography sites
- Screenshots and diagrams where text must stay sharp
- Images that will be further processed downstream
- Print-adjacent work where quality matters more than size
When to choose 1MB vs smaller targets
Choose 1MB when:
- Image quality matters more than file size
- The receiving service accepts files this large
- You want a comfortable margin without visual compromise
Choose a smaller target (100KB, 200KB) when:
- You are uploading to a form with a strict limit
- The image will only ever be shown small
- Bandwidth or storage is a concern
How FITLY reaches 1MB
FITLY starts from the target and works backwards. It probes the image at high quality, measures the result, and only reduces quality or dimensions if necessary to fit under 1MB. If the original is already smaller than 1MB, no re-compression is applied — the tool keeps your file exactly as it is.
The entire process runs in your browser. Nothing is uploaded.
