Page speed cleanup
Shrink oversized images before publishing them to pages, docs, or changelogs.
Documentation
Image Compressor & Resizer documentation
Reduce image dimensions and file size with preset bounds, quality controls, and download-ready previews.
Overview
Use it when the format needs to change, not the meaning
Use Image Compressor & Resizer when an uploaded image needs to weigh less, fit within a target box, or convert into a more delivery-friendly format.
Social and card artwork
Fit one source image into common share-image or card-friendly bounds without guessing the export size.
Hand-off ready assets
Preview the optimized result and download a cleaner file before passing it to another system.
Supported inputs
Bring clean source text and keep the direction straight
- Accepts JPEG, PNG, and WebP uploads up to 5 MB.
- Preset bounds act as maximum width and height limits, while custom width and height values override those limits.
- Animated GIF uploads are not accepted yet because frame-preserving compression is deferred to a later pass.
- Exported files are rewritten without embedded metadata so the download stays focused on the image itself.
Walk through it
Follow the same sequence you see in the tool
Workflow
Resize for the web
Use a preset when you want a predictable maximum size without manually entering dimensions.
- Upload the source image.
- Choose a preset such as web, thumbnail, or social share.
- Run the optimization and review the new dimensions before you download the result.
Workflow
Tune a custom export
Use custom width, height, and output format controls when the next destination has stricter rules.
- Enter a custom width, a custom height, or both.
- Choose the output format and set the quality level you want to test.
- Compare the original and optimized details, then download the file that fits your target.
What you get
Check the result before you copy it into the next step
Preview image
A visual preview lets you confirm the optimized output before you save it.
Original and output details
Dimensions, file size, format, and reduction notes help you judge whether the export is small enough.
Download-ready file
The optimized file is ready to download immediately after the export finishes.
Avoid these mistakes
Small input problems create the biggest conversion errors
Forgetting that limits preserve aspect ratio
Width and height settings cap the image size instead of stretching the image into a new shape.
Using aggressive quality settings on sharp graphics
Screenshots, logos, and UI captures may need a higher quality value or a PNG export to stay crisp.
Reviewing only the preview
Check the file size and dimensions along with the preview so the download matches the delivery target.
Glossary
Decode the terms before you act on them
This section translates the most technical labels on the page into plain language so you can interpret the output without opening another tab.
Compression
Compression reduces file size by rewriting the image data into a more compact form.
Quality setting
A quality setting controls how strongly the export compresses the image and how much detail is retained.
Metadata
Metadata is extra file information such as camera details or edit history that can increase file size without changing the visible image.
Aspect ratio
Aspect ratio is the proportional relationship between width and height that keeps an image from looking stretched or squashed.
