Compress an image to 50KB
Bring an image down to 50KB — a sensible ceiling for thumbnails and listing images, where a page might load twenty or thirty of them before a visitor scrolls.

How it works
- 1
Choose or drag in your image.
- 2
The target is already set to 50KB.
- 3
Click Compress and download the result.
Why use this converter
- Built for grids
Where many images load together, per-image weight multiplies fast.
- Still sharp at thumbnail size
50KB is generous for anything displayed a few hundred pixels wide.
- Pre-set target
No settings to adjust before uploading.
- Batch several at once
Compress a whole set of thumbnails towards the same ceiling.
When to use it
- Product and listing thumbnails: The classic case: many images, one page.
- Category and search result grids: Combined weight decides how quickly the page settles.
- Blog index and card images: Shown small, so they rarely justify more.
- Related-content strips: Below-the-fold images that should never delay what is above it.
Match the file to its displayed size
The most common waste on a website is serving a full-resolution image into a small slot. A 2000-pixel photo displayed in a 300-pixel card is carrying roughly forty times the pixels it needs, and the browser throws away the difference on every single load.
Compressing helps, but resizing to something close to the display size helps far more, and the two together comfortably reach 50KB while looking sharp — including on high-density screens, where roughly double the displayed width is a sensible target.
What this does and does not fix
Image weight is usually the largest single contributor to a slow page, so this is worth doing. But it will not fix render-blocking scripts, slow server response or fonts that delay text appearing.
If images are the problem, the effect is immediate and obvious. If the page still feels slow with light images, the cause is elsewhere and no amount of compression will find it.
Frequently asked questions
Is 50KB enough for a product photo?
For a thumbnail or grid image, comfortably. For a main product image a customer zooms into, choose a larger target — 200KB or more.
Will my thumbnails look blurry?
Not at thumbnail dimensions. Blurriness at this size almost always means the image is still far larger in pixels than it is displayed.
Can I compress a batch?
Yes. Add several images and each is compressed towards the same target.
Does this improve page speed scores?
It improves the image portion, which is usually the largest part. Scripts, fonts and server response are separate matters.
