How to resize and compress an image
- Choose an image. Click the box above and pick a photo or screenshot. A preview and its current size appear straight away.
- Pick a format, quality and width. WebP usually gives the smallest file. Lower quality shrinks WebP and JPEG further. Type a maximum width in pixels to scale it down; the height follows, so nothing is stretched.
- Convert and download. The caption shows the size before and after and the new pixel dimensions. Not small enough? Change a setting and click Convert again, then Download.
Good to know
- Need it under a certain size in KB? There’s no target-size box. Lower the quality or the width a step at a time and watch the result size until it fits the form you’re uploading to.
- Images are only made smaller. A max width larger than the image keeps the original size; it never enlarges.
- Transparency. WebP and PNG keep see-through areas. JPEG can’t, so they are filled with white.
- PNG ignores the quality slider. PNG is lossless, so only a smaller width makes it lighter. For photos, WebP or JPEG is far smaller.
- iPhone HEIC photos work. If your browser can’t read them, the tab loads the libheif decoder on first use. Camera details and GPS location are not copied to the result.
Your images stay on your device
Most online compressors upload your images to their servers. Here, the image is decoded, resized and saved inside this browser tab, using your browser’s own image tools. That matters when you’re shrinking a passport photo, a signature scan or a photo of your ID to fit an application form.
The page’s security policy tells your browser to block uploads, so your image can’t leave your device even by accident. You can check: open your browser’s developer tools, watch the Network tab, and convert an image. How InTheTab works
You’ll also see a few small requests to Google Analytics. That’s our visit counter, and it never receives your files. Privacy policy
Questions
How do I reduce an image’s size in KB?
Pick WebP or JPEG and lower the quality, or type a smaller max width, then click Convert. The caption shows the new size in KB. Repeat until it’s small enough.
What width should I use?
1600 px is plenty for most websites and email. 1080 px suits social media. Phone photos are often 4000 px wide or more, so scaling down alone saves a lot.
Can I resize several images at once?
Not here; this tool works on one image at a time. To turn a batch into JPGs at full size, use Convert to JPG.
Do I need to install anything or sign up?
No. It runs in any modern browser on Windows, Mac, Linux, Android or iPhone. It’s free, there’s no sign-up and no watermark is added.
