Images are processed on your device and are not uploaded. Canvas export removes EXIF, GPS, and most other source metadata. Animated GIF/WebP files are resized as a single still frame.
Fast, Private Image Resizer (Free Online)
If you’re looking for an image resizer free online, this tool keeps everything on your device—no uploads, no sign-ups, no tracking. It handles single images or full batches and exports clean JPG, PNG, or WEBP files in seconds.
Why people use it
- Private by design: All work happens in your browser; nothing leaves your computer.
- Batch friendly: Drop in dozens of files and resize them in one pass.
- Flexible sizing: Fit within a box (contain), fill & crop (cover), set an exact size, scale by percent, or set a longest side.
- Format control: Export as JPG, PNG, or WEBP with adjustable quality.
- Clean output: EXIF and metadata are stripped automatically for smaller, safer files.
- Simple downloads: Save individually, “Download all,” or bundle everything as a ZIP.
How to use
- Upload images (or drag & drop a folder). You’ll see instant previews.
- Choose a mode:
- Contain – fit inside width × height (letterboxes if needed).
- Cover – fill the box and crop the edges (great for thumbnails/headers).
- Exact – force a specific size; enable Lock aspect to avoid stretching.
- Percent – scale by a percentage (e.g., 50%).
- Longest side – set the long edge; the short side follows.
- Select format (JPG/PNG/WEBP) and adjust quality if needed.
- Optionally set a background color for JPG/WEBP when your source has transparency.
- Click Resize, then download files individually, all at once, or as a ZIP.
Practical tips
- Web performance: Use WEBP at 70–85% quality for sharp, small results.
- Logos/UI art: Stay with PNG to preserve crisp edges and transparency.
- Social images: Thumbnails often look best with Cover to avoid pillarboxing.
- Transparency → JPG: Set a brand-matched background color to avoid harsh white boxes.
- Naming: Use the filename pattern (
{name}-{w}x{h}) for tidy exports and easy sorting.
Use cases
- Prepare blog hero images and feature thumbnails in one go.
- Standardize product photos to a consistent box without manual cropping.
- Shrink screenshots before sharing to keep files lightweight and readable.
- Convert bulky PNGs to efficient WEBP for faster page loads.
FAQ
Are my images uploaded anywhere?
No. Everything runs locally in your browser. Files never leave your device.
Why is my output sometimes larger than expected?
Images with lots of detail or noise compress less efficiently. Try WEBP, lower the quality slider slightly, or reduce the longest side.
What’s the difference between “Contain” and “Cover”?
Contain preserves the whole image and may add letterboxing. Cover fills the target box edge-to-edge and crops the overhang.
Does the tool keep EXIF or GPS data?
No. Canvas rendering strips metadata by default, which reduces size and improves privacy.
Which format should I pick?
- WEBP: Best balance of size and quality for the web.
- JPG: Photographs; choose a background color if transparency is present.
- PNG: Logos, UI, or anything needing transparency and crisp edges.
