Compress to about 500KB
Compress images without losing quality
Shrink your images while keeping them looking sharp. Choose WebP or AVIF and a higher quality floor, and the tool does the rest — entirely on your device.
Compress images to about 500 KB
Drop images to compress to ~500 KB
or click to browse — JPG, PNG, WebP, AVIF, HEIC
JPG and WebP usually reach the target size most reliably. PNG is lossless and harder to shrink.
The tool lowers quality and, if needed, dimensions until the file fits under 500 KB.
How to compress images without losing quality
- 1
Add your images
Drag and drop one or more JPG, PNG, WebP, AVIF, or HEIC files, or click to browse. Everything stays on your device.
- 2
Set the 500KB target
The target is fixed at about 500KB. Choose an output format — WebP or JPG usually reach the target most reliably.
- 3
Compress automatically
The tool adjusts quality, then dimensions if needed, until each file fits under 500KB. The exact result is shown per file.
- 4
Download the results
Save each compressed file, or download the whole batch at once. No watermark is added.
What you can do
Automatic size targeting
The tool searches for the best quality that still fits your target, then shrinks dimensions only if it must.
Live before/after sizes
Every row shows the original size and the compressed size so you can see exactly what you saved.
WebP and AVIF support
Next-generation formats reach small sizes with better quality than JPG when your browser supports them.
Nothing is uploaded
Compression runs in your browser, which is faster and safer for personal photos.
Frequently asked questions
Is it really possible to compress without losing any quality?
For photos, some data must be discarded to make files smaller — that is how lossy compression works. The aim here is minimal visible loss: using WebP or AVIF and a higher quality floor keeps the result looking essentially identical to the original while still saving space. For truly lossless files, choose PNG or keep the original.
How do I compress an image to 500KB?
Drop your image above, choose an output format such as WebP or JPG, and the tool automatically lowers the quality — and, if necessary, the dimensions — until the file is at or under 500KB. It shows you the final size for every file.
Will the image quality suffer at 500KB?
It depends on the starting size and the details in the image. Photos with lots of detail need more data, so hitting a small target may soften them slightly. WebP and AVIF usually reach 500KB with less visible loss than JPG. For very small targets, consider reducing the dimensions too.
Are my images uploaded anywhere?
No. Compression is performed entirely in your browser with the Canvas API. Your files stay on your device and are never sent to a server.
What if the image cannot reach 500KB?
For extremely small targets the tool keeps reducing dimensions until it reaches the floor. If a file still cannot meet the target, the row is labelled with the smallest size achieved so you can decide whether that is acceptable.
Which image formats work best for hitting a target size?
WebP and JPG are the easiest to tune because they have a quality setting. PNG is lossless, so the only way to shrink it is to reduce dimensions — the tool handles that automatically but PNG is rarely the best choice for a strict size limit.
