Frequently Asked Questions
Everything you need to know about online image compression, formats, and privacy.
How do I compress a JPG to 100KB?
Upload your JPG, choose a 100KB target, and start compression. The tool tests suitable JPEG settings and, when necessary, adjusts image dimensions to produce a practical file near the requested size. Download the result and verify the final file size before uploading it.
Can I compress a JPEG without losing quality?
JPEG compression is normally lossy, so reducing the file size can remove some image information. The practical goal is to reduce the file enough while keeping the result visually suitable for its intended use without noticeable blur or pixelation.
What is the difference between JPG and JPEG?
JPG and JPEG refer to the same image format. The shorter JPG extension became common because some older MS-DOS systems used three-character file extensions. Both extensions use identical encoding structures and produce identical image fidelity.
Are my images uploaded to a server?
No. All image compression, resizing, and format conversions are performed locally on your device using client-side HTML5 Canvas and browser APIs. Your photos never leave your computer or smartphone, guaranteeing complete privacy.
Why is my JPEG file so large?
Large pixel dimensions from high-megapixel phone cameras, high-quality encoding matrices, sensor grain in low light, and unneeded camera EXIF metadata all contribute to an unnecessarily heavy JPEG file.
How do I compress a photo for an online form?
Online forms typically require images under 100KB or 200KB. Use our dedicated target size tools, select your form's exact threshold, and download the optimized photo ready for submission.
