Compress Image for WhatsApp
Shrink a photo for WhatsApp sharing while keeping the output quick to send and download.
Choose an image
JPEG or PNG, up to 25 MB
1 KB = 1,000 bytes. Transparency becomes white and dimensions may shrink.
Reduce an image to a custom file size
Enter 200 KB, another KB value, or a limit in MB. Filekind searches for a JPEG output at or below that maximum; it does not promise an exactly matching size. This is useful when a photo needs to fit below an upload limit.
- Choose a JPEG or PNG image up to 25 MB.
- Enter the maximum size and choose KB or MB, or use the 200 KB preset.
- Generate the compressed JPEG, then compare its size and dimensions before downloading.
Compression can lower JPEG quality and reduce pixel dimensions when needed. PNG transparency becomes white. File size is the amount of stored data, while dimensions are the image width and height; reducing one does not always reduce the other.
Does this make a lossless image?
No. The output is JPEG, so quality can change and PNG transparency is not preserved.

Questions about this tool
Will WhatsApp compress the image again?
It may. This tool reduces the source file, but WhatsApp controls delivery processing.
Frequently asked questions
Can this make a file exactly 200 KB?
The compressor searches for a JPEG at or below the size you enter and verifies the final file before reporting success. It does not promise an exactly matching size, because JPEG encoding varies slightly between browsers and very detailed photos may need smaller dimensions to reach a small target.
Does compressing reduce image quality?
Usually. The output is a JPEG, so visible quality can drop and PNG transparency becomes white. Reducing dimensions affects file size far more than quality settings alone, which is why the tool may scale a large photo down when a small target is set.
Is my photo uploaded anywhere?
No. Compression runs in your browser with JavaScript, so the file never leaves your device. Filekind only records limited anonymous page-view and click counts, never filenames, file contents, or IP addresses.
What are the size limits?
Images up to 25 MB, 16,000 pixels per side, and 48 megapixels are supported. That ceiling still covers high-resolution photos such as 7,952 by 5,304 pixels.
Can I compress PNG images and keep transparency?
You can choose a PNG as the input, but the output is always a JPEG, so transparency becomes white. If you need a PNG result, compress first and then convert the file back to PNG.
