How to Compress an Image to Under 200KB
200KB is a practical target for most web images — it's small enough to load quickly on mobile connections (under 0.5 seconds on 4G), but generous enough to maintain excellent quality at standard display sizes up to 1200px wide. Shopify product images, WordPress featured images, and most web banners should sit at 200KB or below. Here's how to reliably hit that target.

Step-by-Step Guide

Resize to actual display width first
A 4000px hero image displayed at 1200px is carrying 11× more pixels than needed. Resize to 1200px wide (or 2400px for retina at 1200px display width). This step alone usually gets large images to 200KB without any quality reduction.
Choose the right format
For photos: WebP at 85% or JPG at 85%. A 1200×800px WebP at 85% quality typically lands at 100–180KB. For graphics with transparency: PNG with compression. For anything that needs universal email/print compatibility: JPG.
Compress at 80–85% quality
Open the Image Compressor, drop the resized file, and set quality to 80–85%. Most 1200px-wide photos hit 120–200KB at this setting. The before/after sizes are displayed so you can verify.
Adjust if needed
If still above 200KB at 85%: try 80%. Still above? Try 75% and check for visible artifacts. If the image has very high detail (aerial photos, product close-ups), you may need to reduce dimensions slightly more.
Download and verify
Confirm the file size after downloading. The tool shows the compressed size, but always verify with your OS file info to confirm before uploading to a platform with strict limits.

100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.
Pro tip
Use 75–85% quality for web images — you get 60–80% smaller files with no visible difference at normal screen sizes.
