Question 1

Why is converting web images to WebP recommended over JPG/PNG?

Accepted Answer

WebP is a modern next-generation image format developed by Google:

① Significant File Size Reductions:
WebP images are typically 25% to 35% smaller than comparable JPEGs and over 26% smaller than lossless PNGs.

② Alpha Transparency & Animation Support:
WebP supports transparent backgrounds (Alpha Channel) alongside rich color palettes, drastically speeding up page load speeds and improving Core Web Vitals.

Question 2

Is it safe to process personal portraits, ID cards, or commercial product photos online?

Accepted Answer

100% Private & Secure! The tool operates strictly client-side inside your local browser runtime:

① Zero Cloud Uploads:
All image decodings, Canvas pixel operations, and compression algorithms execute in your computer memory.

② Zero Server Storage:
Your images are never transmitted to or archived on remote servers. It functions reliably even without an internet connection.

Question 3

What is the recommended compression quality setting for optimal results?

Accepted Answer

Balanced recommendations based on deployment targets:

① Web & Social Media (75% ~ 85%):
At around 80% quality, the human eye cannot detect compression artifacts while file sizes are reduced by 60% to 80%.

② High-Res Print & Showcase (90% ~ 95%):
Preserves maximum texture details and color gradation.

③ Real-Time Comparison Slider:
Use our built-in split-view comparison slider to inspect fine details before exporting.

Question 4

What is "Keep Aspect Ratio" and how do I specify custom pixel dimensions?

Accepted Answer

Flexible dimension management tools:

① Keep Aspect Ratio:
When checked, modifying width or height automatically calculates the opposite dimension proportionally without distortion.

② Freeform & Presets:
Uncheck to unlock arbitrary width/height dimensions, or select standard aspect ratio presets (1:1, 4:3, 16:9, 9:16).

Question 5

What input formats are supported? Can I batch-process multiple images into a ZIP archive?

Accepted Answer

Broad format support with batch workflow:

① Supported File Types:
Accepts PNG, JPG/JPEG, WebP, GIF, SVG, AVIF, BMP, and more.

② Batch ZIP Packaging:
Drag and drop multiple images at once, apply unified resizing and compression parameters, and download a bundled ZIP file with one click.

Question 6

How do the Crop and Rotate / Flip tools integrate with the editing pipeline?

Accepted Answer

Visual interactive canvas suite:

① Rotation & Mirroring:
Perform 90° clockwise/counter-clockwise rotations and horizontal/vertical flips instantaneously.

② Interactive Cropping Box:
Drag handles across the canvas to frame your subject; the geometric transformations and crop boundaries are combined cleanly upon export.

Question 7

What should I do when alerted that "Target resolution exceeds original, upscaling may cause blur"?

Accepted Answer

Raster upscaling considerations:

① Interpolation Limitations:
Enlarging raster bitmap pixels beyond native sensor resolution forces browser algorithms to generate synthetic pixels, potentially causing softness.

② Best Practices:
Prioritize downscaling or preserving native resolution; for vector artwork, use SVG assets when infinite scalability is required.
