Om dette verktøyet

The Image Size Reducer is a tool designed to help creators publish media efficiently. It accepts common image formats and outputs a resized, compressed version suitable for web and app use. It focuses on preserving visual fidelity while reducing bandwidth and storage requirements. The tool handles dimension-based resizing, optional format conversion, and quality controls to balance file size with quality. It is well-suited for developers deploying assets to websites, marketers optimizing galleries, and product teams preparing images for catalogs.
Conceptually, the tool reads the source image, computes new pixel dimensions based on target width/height or a scale factor, and then applies a chosen compression method for the selected format. It can preserve aspect ratio by default and can remove metadata when requested to further lower file size. Output includes the resized image, the new dimensions in pixels, and the resulting file size estimate to help decisions during publish workflows.
Unique value lies in its simple workflow for batch resizing, its clear controls for preserving aspect ratio, and its ability to convert between JPEG, PNG, and WEBP while applying quality settings. This makes it valuable for teams that publish diverse media across platforms with strict size constraints. Common use cases include hero images for product pages, thumbnails for galleries, and assets for email campaigns or social posts where bandwidth is limited.

Frequently Asked Questions

Finn raske svar

Which formats are supported for input and output?
Input supports JPEG, PNG, and WEBP. Output can be JPEG, PNG, or WEBP depending on the chosen settings. The tool preserves transparency for PNG/WEBP when applicable.
How is the final image size determined?
The tool uses target width/height or a scale percentage to compute new dimensions, then applies a chosen compression level to produce the final file size. Aspect ratio is preserved by default.
Can I batch resize multiple images at once?
Yes. Use the file upload area to select multiple images. The tool processes each file independently and outputs corresponding resized assets, suitable for batch workflows.
Is metadata removed during resizing?
Metadata stripping is available as an optional feature. By default, metadata may be retained unless you enable stripping to reduce size further.
Can the tool upscale images if needed?
Upscaling is not performed by default to avoid quality loss. Up-scaling can be enabled only if explicitly requested, but results may vary based on content and format.
