Frequently asked questions

Why compress an image to under 1MB?

1MB is a common threshold for email attachments, CMS media libraries, and document upload portals. Keeping images under 1MB also noticeably improves web page load times.

Is 1MB a large or small file size for an image?

It depends on the image. A 1MB JPG at typical web dimensions (1200×800px) has excellent quality. A raw photo from a modern smartphone can be 5–15MB, so compressing to 1MB typically produces a visually identical result.

Does Resizeify keep aspect ratio intact?

Yes. When Resizeify needs to reduce dimensions to reach the target size, it always maintains the original aspect ratio — your image won't be stretched or cropped.

Can I compress a PNG to under 1MB?

PNG can usually reach 1MB more easily than smaller targets, since PNG is lossless and the target is more generous. For very large PNGs, switching to WebP output will give you the best quality-to-size ratio.

How long does compression take?

Typically under 2 seconds for most images. Very large originals (10MB+) may take 3–5 seconds as the tool runs multiple quality iterations to hit the target precisely.
