Free Online Image Tools – Convert, Compress & Resize

Convert, compress, resize and edit images, read or remove EXIF metadata, optimize SVG files and create favicons, QR codes and placeholders — without uploading your pictures anywhere.

Online image tools that keep your photos on your device

Every tool in this collection processes images inside your browser using the built-in canvas and file APIs. Your photos are never uploaded to a server, so there is no waiting for uploads, no file-size quota and no copy of your pictures left on someone else's machine. That makes these online image tools a good fit for screenshots of internal dashboards, product photos before launch, or personal pictures you would rather not share.

Which image tool do you need?

Change the file format. Use JPG to PNG when you need lossless edits or transparency later, PNG to JPG to shrink photos for email, and PNG to WebP or JPG to WebP for faster web pages.
Make files smaller. The image compressor lets you trade quality for size with a live before-and-after preview, and the image resizer scales large camera photos down to the dimensions your site actually displays.
Edit and prepare. Crop, rotate, flip or apply filters before publishing.
Privacy clean-up. The EXIF viewer shows camera model, date and GPS location stored in a photo; the EXIF remover strips it before you share the file.
Website assets. Generate a complete favicon set, optimize SVG icons with the SVG optimizer, or create placeholder images for mock-ups.

Choosing the right format

Format	Best for	Transparency	Compression
JPG	Photos	No	Lossy, very small files
PNG	Screenshots, logos, UI	Yes	Lossless, larger files
WebP	Web images of any kind	Yes	Lossy or lossless, usually smallest
GIF	Simple animations	1-bit	256 colours only
SVG	Icons and illustrations	Yes	Vector, scales without blur

Tips for better results

Resize before you compress: halving the width and height removes three quarters of the pixels, which saves far more than lowering JPG quality. Keep an original copy, because every lossy save throws detail away. For images shown on retina screens, export at twice the displayed size and let the compressor bring the file size back down.

Converters read only the first frame of an animated GIF and do not carry over EXIF metadata, so check the output if either matters to you.

Frequently asked questions

Are my images uploaded to your server?

No. All image tools run in your browser using the canvas and File APIs, so the pictures never leave your device.

Is there a file-size limit?

There is no fixed limit, but very large images (for example 50 megapixels) depend on your device's memory. Resizing first keeps things fast.

Which format gives the smallest files for the web?

WebP is usually the smallest at a similar visual quality, followed by JPG for photos. Use PNG when you need lossless quality or sharp text.

Do the converters keep transparency?

Yes when the target supports it (PNG, WebP). Converting to JPG or BMP fills transparent areas with a solid background because those formats have no alpha channel.
