Frequently Asked Questions
Why is 100KB the standard target size for web publishing and email attachments?
An image under 100KB loads virtually instantaneously on mobile 4G/5G connections and keeps web pages fast and responsive. It also complies with email attachment size limits and prevents inbox clutter while maintaining sharp photographic detail on desktop displays.
How much visual quality is lost when compressing a 5MB photo to 100KB?
Because smartphones capture photos at massive 12MP to 48MP resolutions with heavy uncompressed data, resizing to standard HD (e.g., 1200x800 px) and applying modern JPEG compression preserves sharp visual quality while shedding 98% of the file size.
Can I compress multiple images to 100KB in batch?
Yes. You can upload a batch of photos, and the compressor will optimize each image individually to ensure every file stays under the 100KB threshold.
Is there any risk to my privacy when compressing sensitive documents?
No. The entire process runs locally within your browser sandbox. No images are uploaded to any external server.
