Image File Size Calculator – Estimate image file size based on resolution
The image file size calculator estimates image file sizes based on pixel resolution, color depth, and compression type (RAW, TIFF, PNG, JPEG). Useful for storage planning and web image optimization.
Enter image width and height in pixels plus file format, and the calculator estimates file size in megabytes. For JPEG compression, you can also adjust quality settings and see the quality vs. size tradeoff.
How much space do 1000 photos take?
Modern DSLR RAW images take about 25–45 MB each. JPEG from the same camera is about 8–15 MB. 1000 RAW images require approximately 25–45 GB storage. Smartphone HEIC images are about 3–5 MB, JPEG about 4–8 MB. The image file size calculator estimates precise sizes with your selected settings.

Enter image dimensions, color depth, and format – the calculator estimates file size in megabytes.
- Estimate raw image file and compressed file sizes.
- Compare how different formats (JPEG, PNG, WebP) affect file size.
- See how reducing resolution affects size.
Actual compressed image size depends on image content – the calculator provides an estimate.
- JPEG compression is efficient for photographs, PNG works better for graphics and text.
- Actual file size may differ from estimate depending on image detail.
- WebP format usually offers the smallest file size while maintaining quality.
Image optimization is important for website loading speed and storage space.
- Excessive compression visibly degrades image quality.
- For web use, image optimization improves site performance and SEO.
- Calculator gives theoretical estimate – always test different settings in practice.
