Compress an image to 500 KB
Drop a photo and get it back just under 500 KB — the size asked for by blog images and content management systems. Free, and the photo is never uploaded.
Each file lands just under this size.
If quality alone can't reach the size, the image is scaled down until it fits. The new size is shown on the file.

About compressing to 500 KB
500 KB is a practical ceiling for images on a website. Most content management systems and page builders will accept far more, but pages built from megabyte images are the reason so many sites feel slow on a phone.
At this size you can keep a wide hero image sharp — around 1600 to 1920 pixels across — without the weight. If you're publishing regularly, it's worth running every image through a target like this before uploading.
For a photograph, consider WebP rather than JPG when the destination is your own site: it reaches the same quality in roughly a quarter less space, and every current browser reads it.
Image weight is the usual reason a page is slow to show its main content, and the largest image on the page is often what search engines time when they measure it. Keeping the hero image well under 500 KB, and the rest of the page's images smaller still, is one of the simplest speed wins there is.
Most content management systems make smaller copies of each upload, but they also keep the original, and some themes, galleries and link previews still serve it. Uploading a 500 KB file instead of a 5 MB one means nothing heavy is ever sent, whichever copy ends up on the page, and your storage and backups stay lighter too.

How to use it
- 01Drop your image, or paste one with Ctrl+V. JPG, PNG, WebP and HEIC all work.
- 02The target is already set to 500 KB — change it if your form asks for something else.
- 03Tap Compress. Quality is lowered step by step, and the photo is scaled down only if that's the only way to reach 500 KB.
- 04Compare the result with the original, then download.
Compressing images, answered
Why not upload the original and let my CMS resize it?
The CMS usually keeps the original alongside its smaller copies, and some themes, lightboxes and social previews serve the original anyway. Starting from a 500 KB file means the heaviest version anyone can be sent is still reasonable.
How do I make a photo exactly 500 KB?
Drop it above and tap Compress. The target is already 500 KB, and each file comes back just under that — the quality that was needed is shown on the file, so you can see how hard it had to work.
Will my photo still look good at 500 KB?
Usually yes. At 500 KB a full-size photo keeps its detail, and most people can't tell it apart from the original.
What if the form also wants exact dimensions?
Resize first, then compress. The resize tool has presets for passport photos (35 × 45 mm) and common pixel sizes, and compressing afterwards keeps those dimensions unless the size target can't be met any other way.
Why does the form ask for 500 KB?
Upload limits keep storage and bandwidth predictable — 500 KB is a common one for blog images and content management systems. The limit is about the file size in kilobytes, not how large the photo looks on screen.
Is my photo uploaded anywhere?
No. Compression runs in your browser, so the photo never leaves your device — which matters when you're sending ID documents to a form.
