Frequently Asked Questions About Image Utilities
Which image formats can I compress and convert on DwellixTools?
Our image tools support all primary web standards including WebP, AVIF, PNG, JPEG, SVG, and GIF, with options for lossy and lossless compression.
What compression quality setting is recommended for Core Web Vitals?
For web photography and banners, a quality setting between 75% and 85% delivers an optimal balance between significant file size reduction (typically 60% to 80% savings) and crisp visual clarity.
Does the image compressor preserve transparent PNG backgrounds?
Yes. When converting or compressing PNG images to WebP or PNG format, 8-bit alpha transparency is fully preserved. Selecting JPEG format will replace transparent regions with a solid white background.
Are my personal photos, passport pictures, or scanned documents uploaded to a server?
No. All image decompression, canvas resizing, color quantization, and re-encoding process locally inside your web browser using HTML5 Canvas and OffscreenCanvas APIs. Your photos never leave your device.
Can I compress multiple images simultaneously in batch mode?
Yes. Drag and drop up to 20 images into the upload zone to compress them in parallel, with individual downloads or a single consolidated .zip archive export.
