Upload your image
JPG, PNG and WEBP are supported. Processing happens in your browser.
Target size presets
Your photo stays on your device. Compression runs in your browser and no file is uploaded to our server.
What this tool does
Upload a JPEG, PNG, or WebP image and enter a target file size in KB. The tool compresses the image to fit within that limit using intelligent quality adjustment, then lets you download the compressed JPEG file. Processing is done entirely in your browser.
When to use it
Use this when a portal rejects your photo because it is too large. Common limits are 20KB, 50KB, and 100KB. After compressing, verify the dimensions still meet requirements — use Document Photo Resizer if you also need to adjust the pixel size.
Frequently Asked Questions
How does this photo compressor work?
It reduces the file size of your image by lowering the JPEG quality setting until the file fits within your target size in KB. The visual quality reduction is usually minimal for target sizes above 20KB.
What is the minimum size I can compress to?
You can compress to as low as 10KB, though very aggressive compression will visibly reduce photo quality. For official document photos, 20–50KB usually maintains acceptable quality.
What formats are supported?
Upload JPEG, PNG, or WebP images. The compressed output is downloaded as JPEG, which is required by most government portals and online forms.
Is my photo uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API. Your photo never leaves your device.
Why do government portals have such small file size limits?
Most government portals were built with older infrastructure and set limits like 50KB or 100KB to reduce server storage costs and upload times. This tool helps you meet those limits without specialised software.
