Key Features

Export as JPG, PNG or Webp (and other common formats depending on your browser support).
Choose JPG for smaller web size; choose PNG for transparency or sharp graphics. (Webp for lowest file size)
3) Quick downloads
One‑click Download saves the processed file instantly.
Filenames preserve original name with a clear suffix so you don’t lose track.
4) Designed for the modern web
Crisp results suitable for posts, social media, portfolios, and e‑commerce listings.
Helpful defaults that keep quality reasonable and file sizes web‑friendly.
5) Quality Slider
When exporting images, the Quality Slider lets you balance between file size and clarity. A higher setting (80–100%) preserves maximum detail, ideal for photography and design work. Lower settings (50–70%) reduce file size significantly, making images web-friendly and faster to load while still looking sharp for everyday use.
6) Modes: Stretch, Contain, Crop
The Image Resizer offers flexible resize modes depending on your needs. Stretch forces the image to fit the exact width and height, even if it distorts proportions. Contain ensures the entire image fits inside the chosen dimensions, adding blank space if necessary. Crop fills the target area while trimming any overflow, making it perfect for fixed-ratio formats like 16:9 banners or 1:1 profile pictures.
Note: Exact controls may evolve as we keep improving the tool. This guide covers the typical flow and common options.

Pro tips
If you only change Width, Height auto‑adjusts (and vice‑versa) when the aspect lock is on.
For website images, aim for widths like 1200px (article feature), 800–1000px (content images), 400–600px (thumbnails), depending on layout.
Avoid upscaling small images too much; it can look soft.
B) Convert JPG ↔ PNG (and more)
1. Add your image.
2. Look for Output Format.
3. Pick Wepb(Smallest), JPG (smaller files) or PNG (supports transparency).
4. Download.
Choosing formats
PNG: Logos, UI, product shots with transparency, crisp text.
JPG: Photos, blog images, social media — smaller size.
Webp: Use in Websites for faster loading – Recommended by Google

Best Practices for Quality & Speed
Downscale rather than upscale. Upscaling can blur details.
Keep a master copy of your originals.
For the web, target images under 200–400 KB where possible (PNG may be larger).
Use descriptive file names (e.g., red-running-shoes-1200×800.jpg).
Use Quality Slider to Maintain Quality & File Size.
Troubleshooting
Image won’t load? Ensure the file is a common format like JPG/PNG/Webp and not corrupted.
Orientation issues? If a photo appears rotated, re‑export after rotating in your gallery app, then resize.
Huge downloads? Prefer JPG or Webp and consider slightly smaller dimensions.
Looks stretched? Turn on Aspect Ratio lock before changing size.
Transparency lost? Use PNG export for graphics with transparent backgrounds.
