Question 1

How does the Image Compressor reduce file size?

Accepted Answer

The compressor optimizes image data by removing unnecessary file metadata and applying efficient compression algorithms suited to your chosen format (JPG, WebP, or PNG). You can adjust the visual quality slider or specify a target file size to balance clarity against file weight.

Question 2

How can I compress an image to an exact KB size (like 50 KB or 100 KB)?

Accepted Answer

Switch to the "Target File Size (KB)" mode inside the tool and select a preset threshold (such as 50 KB, 100 KB, 200 KB, 500 KB, or 1 MB) or type a custom number. The compressor automatically calculates the optimal quality setting to achieve your required file size limit.

Question 3

Does compressing an image reduce its visual quality?

Accepted Answer

Mild compression (around 70% to 85% quality) strips high-frequency pixel noise and redundant metadata with virtually no visible difference to the human eye. Aggressive compression to extremely low file sizes may introduce slight softening or artifacts, but you can preview results in real time before downloading.

Question 4

Does compressing an image change its pixel dimensions?

Accepted Answer

In standard quality mode, compressing an image maintains the exact original pixel width and height. When compressing down to extremely small target file sizes (such as under 50 KB from a multi-megapixel photo), slight dimensional scaling may be applied automatically if quality reduction alone cannot meet the constraint.

Question 5

Which format gives the smallest file size: JPG, PNG, or WebP?

Accepted Answer

WebP typically produces the smallest file sizes, delivering 25% to 35% better compression than JPG at equivalent visual quality while supporting transparency. JPG is best for photographic pictures, while PNG is ideal for graphics, line art, and illustrations requiring lossless transparency.

Question 6

Why is my compressed PNG file still larger than a JPG?

Accepted Answer

PNG uses lossless compression designed to preserve every single pixel perfectly, making it inherently heavier for complex photos. If you need a significantly smaller file size for a photograph, consider converting it to JPG or WebP in the tool settings before downloading.

Question 7

Are my photos secure when using the compressor?

Accepted Answer

Yes. The compression engine runs 100% locally inside your browser using HTML5 Canvas. Your images are never sent over the internet to any external server, guaranteeing total privacy for personal photos, receipts, or official identity documents.
