Compress image to 500KB
Shrink large photos to a 500KB ceiling while preserving useful resolution and detail.
Exact-size compressor
Files stay on this device
Advanced settingsResize, crop, quality
Dimensions never upscale. JPEG fills transparent pixels with white. GIF and animated WebP inputs become a static first frame.
Ready when you are. No image data is sent over the network.
On-device processing
No image upload endpoint exists.
Measured output
Success uses the real output bytes.
Batch ready
Process 20 files and download a ZIP.
Pick the limit your form asks for
Every page uses the same private compressor with the target already selected. You can still enter a custom value at any time.
A strong web and sharing budget
Five hundred kilobytes can retain high visual quality for many screen uses. The compressor still measures the real file size instead of relying on a rough quality preset.
Where this target helps
High-quality web images and content uploads
Product photos and portfolio samples
Smaller attachments for email and messaging
Highest useful quality, without guesswork
Search quality first
JPEG and WebP outputs use a binary search to find the highest encoder quality that stays below 500KB.
Resize only when required
If quality alone cannot reach the limit, the engine reduces dimensions and searches again. It never upscales the source.
Show the honest result
Every download reports its measured bytes, dimensions, savings, and whether the requested maximum was reached.
Choose the right format
- JPEG
- Broadly accepted and efficient for photographs. Transparency becomes white.
- WebP
- Often smaller at similar quality and can preserve transparency.
- PNG
- Lossless and good for sharp graphics, but harder to fit under tiny limits.
Questions before you compress
Can a multi-megabyte photo stay full size at 500KB?
Often yes, but it depends on resolution and visual complexity. Detailed or noisy images may need a modest dimension reduction.
Can I set a smaller custom value from this page?
Yes. Select Custom and enter any target between 5KB and 10MB.
Is there a watermark or daily limit?
No. The tool adds no watermark and does not require an account or usage quota.
Your images stay yours
The compressor has no image upload API. Analytics, when allowed, records only page and tool events without file names or contents.
