File format, compression, pixel dimensions, and metadata are separate concerns. Choose conversion, compression, resizing, or web optimization according to the actual delivery goal.

Lossy and lossless compression

JPEG and lossy WebP discard image information to reduce size. PNG preserves transparency and crisp edges but can be inefficient for photographs.

Choosing a format

JPEG or WebP often suits photos, PNG or WebP suits transparency and interface graphics, and AVIF or WebP can improve web delivery when support is confirmed.

Pixels versus file size

Dimensions describe resolution; KB and MB are encoding results. Identical dimensions can produce very different sizes depending on format, quality, and image complexity.

Re-encoding and quality

Conversion and resizing usually re-encode the image. Repeatedly saving lossy formats can accumulate blocking, smearing, and edge damage.

Metadata and color

EXIF, GPS, and ICC profiles are separate from visible pixels. Browser re-encoding may remove metadata or change color appearance.

Tool boundaries

Use a converter for format changes, a compressor for file size, a resizer for dimensions, and a web optimizer for a complete delivery workflow.
