Compress Image to 500KB Online
Reduce JPG, PNG, WebP, and HEIC images to 500KB or less without manual trial and error. Smart binary-search keeps quality as high as possible while hitting your exact size limit.
Drop images here or click to upload
Supports JPG, JPEG, PNG, WebP, and HEIC. Multiple files at once.
Images are processed locally in your browser. Nothing is uploaded.
Why 500KB?
Forms & portals demand it
500KB is one of the most common upload caps on government, exam, and HR portals. Going over by even 1KB rejects the file.
Faster sharing
At 500KB per image, emails and chats stay snappy and uploads finish in seconds even on slow mobile networks.
Quality you can trust
Our quality-search algorithm preserves the highest possible fidelity while staying inside the 500KB envelope.
How to compress an image to a specific size
Upload your images
Drag and drop one or many images, or click to browse. JPG, PNG, WebP, and HEIC are all supported.
Pick a target size
Choose a preset like 100KB, 500KB, or 2MB — or type any value in KB. The tool aims for that exact size.
Let the algorithm work
A binary search across JPEG / WebP quality finds the highest fidelity that fits your target. If needed, dimensions are reduced too.
Download your files
Download images one at a time, or grab them all as a ZIP. Filenames include the target size for easy organization.
Frequently asked questions
How can I compress a photo to exactly 500KB?
Upload the image, choose 500KB (locked on this page), and the tool runs a quality binary search across JPEG/WebP encoders to land inside the 500KB limit while keeping quality as high as possible.
Will the image quality look acceptable at 500KB?
For most photos compressed to 500KB, the difference is barely visible. Detail-rich images (4K landscapes, fine text) may show slight softening — try WebP output for a small extra-quality boost.
Does this change my image dimensions?
Only if quality alone cannot reach the target. You can disable dimension downscaling in the settings panel if a portal requires fixed resolution.
Are my images uploaded?
No. Everything happens in your browser using Canvas APIs. The page also works offline once loaded.
Can I batch-compress many photos at once?
Yes. Select multiple images at once and download all compressed results as a single ZIP archive when finished.
