Frequently Asked Questions
Can I compress an image to exactly 100KB?
Often yes, especially for JPG and WebP files. If the exact target cannot be reached because of the original format, dimensions, or quality limits, the tool shows the closest best-effort result.
Which image formats are supported?
The tool supports common image formats including JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC.
Should I allow format change?
Allowing format change can make it easier to hit smaller targets because formats like JPG or WebP are often more size-efficient than PNG. Keep the original format when you have strict format requirements.
Is this image size reducer private?
Yes. Image processing happens locally in your browser, so your files are not uploaded to a server.
What is the maximum image file size I can compress?
There is no fixed server limit because everything runs locally, but most devices comfortably handle photos up to about 30MB and 8000 pixels wide. If a huge file fails or slows down, resize it to around 3000 pixels first, then compress it to your target size.
Does compressing to a target size reduce the image resolution or dimensions?
Often yes. The tool lowers JPEG quality first, and if the file still exceeds your target, it scales dimensions down in steps until it fits. Small photos usually keep full resolution, while large ones may end up 1500 to 2500 pixels wide. Allowing a format change preserves more detail.
Why is my compressed file slightly over or under the target size?
The tool adjusts quality in small steps, so results typically land within about 1 to 2 per cent of your target. Strict forms may reject a file at 101KB, so if the limit is firm, pick a target roughly 5 per cent lower, like 95KB for a 100KB requirement.
Does compressing remove EXIF metadata like GPS location?
Re-encoding in your browser normally strips EXIF metadata, including GPS coordinates, camera model, and the capture date. This trims a few kilobytes and protects your location when uploading profile or ID photos. The visible image stays identical, with the same pixels, colours, and dimensions after compression.
