Image Compressor

Compress images into smaller JPEG or WebP files, compare size savings, and download the optimized result.

Last reviewed: June 11, 2026

About this tool

Compress images for the web when you need smaller upload sizes, faster page speed, or lighter content handoff without leaving the browser.

Image Compressor is most helpful when file size matters more than pixel dimensions. It lets you compare the original and compressed result side by side so you can trade off quality and savings deliberately instead of guessing.

  • Compresses uploads into JPEG or WebP output.
  • Shows original and compressed previews side by side.
  • Displays the file size savings before download.

How to use Image Compressor

Upload an image, choose the output format and compression level, then compare the previews and size savings before downloading. If the visual loss is too noticeable, step back the compression slightly instead of chasing the smallest possible file.

When this tool is useful

  • Reduce image file size before uploading to a CMS, email platform, or website.
  • Create lighter JPEG or WebP assets for faster page delivery.
  • Compare quality loss against file-size savings before final export.

Practical tips

  • Resize first if the image is much larger than the final display size.
  • Use WebP when you want stronger compression and the target platform supports it.
  • Do not over-compress hero or product imagery just to maximize the savings percentage.

Examples you can test

These examples show the kind of real input and reviewed output this tool is designed to support. Use them as a starting point before pasting your own production content, then compare the output with the destination system that will use the result. The goal is not only to produce a value, but to make the input assumptions, output format, and review step clear enough that the result can be trusted in a real workflow.

Compress a blog hero image

Example input

Source: 1800px JPEG, quality: 75

Expected output

Smaller JPEG suitable for web publishing

Compression can improve page load speed, but the final image should still be visually inspected.

Reduce a screenshot for documentation

Example input

Source: PNG screenshot, target size reduction

Expected output

Compressed image with lower file weight

Screenshots need enough clarity for UI text, so avoid aggressive compression.

Validation checklist

Run through these checks before copying the result into a CMS, codebase, spreadsheet, campaign, support ticket, or production document. Small formatting differences, unit assumptions, hidden whitespace, and platform-specific rules are common sources of mistakes in quick browser tools, so the final review should happen in the same context where the output will be used.

  • Compare the compressed image with the original before replacing assets.
  • Check file size, dimensions, and visual clarity after export.
  • Keep the original source file in case compression settings need to change.

Why people use this tool

Compression is a practical publishing task tied to page speed, upload limits, and content ops. A good compression page makes the weight savings obvious while still keeping the visual decision in front of you.

Frequently asked questions

Can I choose JPEG or WebP output?

Yes. You can switch between JPEG and WebP before generating the compressed result.

Will I see the new file size before downloading?

Yes. The tool shows the compressed file size and the percentage saved.

What is the maximum file size I can upload for compression?

The compressor handles uploads up to 20 MB per image. Processing happens locally in your browser, so larger files may take a few extra seconds depending on your device speed.

How do I choose between JPEG and WebP output formats?

Use JPEG when you need universal compatibility across older email clients and CMS platforms. Choose WebP when targeting modern browsers, as it typically produces 25-35% smaller files at the same visual quality.

Does compression strip EXIF metadata from photos?

Yes, EXIF data including GPS coordinates, camera model, and timestamps is removed during compression, which reduces file size and also protects your location privacy.
