Reduce the file size of photos by setting a quality or a target size such as 100 KB. Nothing is uploaded.
Your photos never leave this device. Nothing is uploaded.
This browser cannot run the converter (it needs Web Workers and WebAssembly). JikImage has been tested in current Chrome and Edge; Firefox and Safari have not been checked yet.
Drop photos here
or choose files. HEIC, JPG, PNG, WebP and AVIF are supported.
Saving straight into a folder works in Chrome and Edge. Here the results are downloaded as a file, or as one ZIP file for several.
The conversion programs (codecs) are files of this website. Your browser downloads them from jiktools.com when needed; these requests contain no image content and no file names.
How to use
Add your photos.
Set the quality, or choose a target file size.
Save the smaller files into a folder or download them. Compare the sizes in the list.
Frequently asked questions
?Are my photos uploaded?
No. Conversion runs inside your browser on your device. Your images, their names and the information in them are not sent to JikTools. Only the conversion programs (codecs) are downloaded from jiktools.com, and those requests contain no image content or file names.
?Will the quality get worse?
JPG, WebP and AVIF are lossy formats, so saving them again changes the pixels slightly; the recommended setting keeps the difference hard to see. PNG keeps every pixel. Check the results before you delete the originals.
?How does the target file size work?
JikImage tries several quality levels and keeps the best one that fits your size. If even the lowest quality is too big, the smallest result is saved and the row says the target was not reached.
?Is the location kept in converted photos?
By default the location (EXIF GPS), XMP and IPTC are removed. Other camera information such as the date and model can stay. Each result row shows "No EXIF/XMP/IPTC location data" only after the finished file was read again and no location was found.

This picture uses a colour mode that cannot be converted (such as CMYK).
The target size could not be reached; the smallest result is saved.
A target size does not apply here (PNG output or saving without re-encoding); it was ignored.
The photo was not enlarged.
Transparent areas were filled with the background colour.
AVIF cannot store EXIF, so camera information was not carried over.
The colour profile was not carried over.
The result is larger than the original.
The rotation setting was kept instead of turning the pixels.
Extra images stored after the main picture (for example a preview) were removed, because they can carry their own location data.

Keep
Keeps the camera information (EXIF), including the location, as far as the result format can store it.
Remove location data
Removes the location (EXIF GPS), XMP and IPTC. Other information such as the date and camera model stays.
Remove EXIF, XMP, IPTC and comments
Removes EXIF (location included), XMP, IPTC and text comments. The colour profile stays, and so does the rotation if the photo needs it.
