Frequently Asked Questions
How does this tool hit an exact target size?
It automatically searches through compression quality levels to get as close as possible to your chosen target size, then falls back to slightly reducing dimensions if needed.
Why isnt the result exactly my target size?
Image content affects how small a file can get. The tool always returns the closest achievable size at or under your target without needlessly destroying quality.
What image formats are supported?
JPG and PNG images are supported. The output is always returned as a JPG, since JPG compression is what makes hitting an exact target size possible.
Can I compress multiple images at once?
Yes. Upload as many images as you need and each one will be compressed toward your chosen target size and returned in a single download.
Is there a file size or file count limit for uploads?
Each uploaded file can be up to 50MB, and you can upload up to 50 files in a single batch.
Is it safe to upload personal photos?
Yes. Uploads happen over an encrypted connection, and both the source image and the compressed result are automatically deleted from our servers after processing.
Is Compress Image to Size free to use?
Yes. There is no cost, no subscription, and no account required.
Can I use this tool on my phone?
