Best starting points in Image tools

These tools are surfaced from the category decision guide, so they match the most common tasks before the full list below.

Which image tool should I use?
Start with the final asset problem: framing, size, format, metadata, color, or publishing composition.
Frame or crop a visualImage Crop Tool
Open tool

Use this when the image has the right content but the wrong crop, ratio, or focus area.

Next: Resize after cropping so the final pixel dimensions match the target surface.

Processing: Browser canvas export.

Resize an image for a target slotImage Resizer
Open tool

Use this when a page, marketplace, README, or social layout expects fixed pixel dimensions.

Next: Compress the resized file after dimensions are final.

Processing: Browser-side image resize.

Reduce file sizeImage Compressor
Open tool

Use this when upload limits, page weight, or sharing speed matter more than perfect source quality.

Next: Compare quality settings before replacing the original.

Processing: Browser-side compression and re-export.

Change image formatImage Format Converter
Open tool

Use this when a platform needs JPG, PNG, WebP, or AVIF rather than the source format.

Next: Check transparency before converting PNG to JPG.

Processing: Browser-side format conversion.

Inspect or remove metadataImage Metadata Inspector / EXIF Remover
Open tool

Inspect first when you need dimensions, transparency, animation hints, or EXIF presence before sharing.

Next: Use EXIF Remover before public sharing when metadata should not travel with the file.

Processing: Metadata read and canvas re-export in the browser.

Create publishing visualsImage Collage Maker
Open tool

Use collage, grid, watermark, and color tools when the output is a shareable visual asset, not just an edited file.

Next: Compress the final composed image before publishing.

Processing: Browser-side layout and export.

Common mistakes
  • Compressing before cropping or resizing, then compressing again after every edit.
  • Converting transparent PNG assets to JPG without checking the background.
  • Publishing screenshots without checking dimensions, metadata, and file size.
  • Using a decorative collage when a single cropped image would communicate faster.
