What Image Studio Can Do

Every Image Operation in One Tool

No more switching between different tools — Image Studio handles your entire image workflow.

🔄 Convert to WebP

Convert PNG and JPG to WebP with lossy or lossless encoding. Quality control from 1–100. Smaller files, better web performance, improved Core Web Vitals.

⤢ Resize Images

Scale by width, height, percentage or fit inside a bounding box. Preserves aspect ratio automatically. Optional upscaling control.

🔃 Rotate & Flip

Rotate 90°, 180° or 270° clockwise or counter-clockwise. Flip horizontally, vertically or both. Applied to every image in your batch.

✂️ Crop to Ratio

Centre-crop to square, 16:9, 4:3, 9:16 or 3:2 aspect ratios. Perfect for social media thumbnails, product images and blog headers.

✨ Image Filters

Apply grayscale, sepia, invert, vintage, cold or warm filter presets. Fine-tune with individual brightness, contrast, saturation and blur sliders.

💧 Text Watermark

Add custom text watermarks to every image. Choose position, opacity and color. Great for protecting your photography or branding exported assets.

📦 Batch & ZIP

Process unlimited images in one run. Download files individually or bundle everything into a ZIP archive with a custom filename and prefix.

🔒 100% Private

Every operation — conversion, resize, crop, filter — runs locally in your browser using JavaScript Canvas API. Your images never leave your device.

⚡ No Limits

No file count cap, no daily limits, no premium plan. Process as many images as your browser can handle, completely free with no account needed.

FAQ

Image Studio FAQ

Does Image Studio upload my files?

No. All processing — conversion, resize, crop, rotate, filters, watermark — runs entirely in your browser using JavaScript and the HTML5 Canvas API. Your files never touch any server.

What image formats can I convert to?

Image Studio converts PNG and JPG/JPEG images to WebP format. More output formats (PNG, JPEG, AVIF) are coming in future updates.

How many images can I process at once?

There is no enforced limit. You can drop hundreds of images at once. The practical limit is your browser's available RAM, which is typically enough for hundreds of images.

Can I apply multiple operations at once?

Yes. All settings across all tabs are applied simultaneously during conversion — so you can convert to WebP, resize, rotate, crop, add a watermark and apply a filter all in one pass.

What does the Crop feature do?

Crop removes pixels from the edges of each image to match the selected aspect ratio, centred on the original image. Great for creating consistent thumbnails or social media images.

Can I watermark images with a logo?

Currently Image Studio supports text watermarks. Image/logo watermark support is planned for a future update.

Also Try the Dedicated WebP Converter

Need just WebP conversion? The standalone WebP Converter is focused, fast and includes extra options like lossless encoding and custom background fill.
