WORKLAZY TOOLS

Online Photo Editor

A versatile photo editor providing image resizing, cropping, mosaic, filtering, and free-hand drawing features.

Use this tool directly in your browser without installing software or signing in.

Integrated Image Editing

Open a photo or start with a blank canvas to use adjustments, drawing, text, shapes, and searchable stickers within one work history. You can change the entire content or canvas size separately and specify the export pixel size. Zoom in with the mouse wheel, drag while pressing Space to move, and use two fingers to zoom and move on mobile.

Area Mosaic / Blur

You can drag areas to obscure in the photo and adjust the effect intensity. The effect applies based on the original photo, so if areas overlap, the last effect is visible. It does not apply to separately drawn lines or text. For sensitive information, a strong mosaic is recommended over a low-intensity blur. Before downloading, zoom in to check the obscured state.

Batch Processing

Add multiple files and clipboard images to apply resizing and watermarks, and bundle them into a ZIP.

Collage and GIF

Provides downscaled previews equal to the actual output calculation, and GIFs may have simplified color changes due to the 256-color limit.

What is the difference between image size and canvas size?

Changing the horizontal and vertical pixels alters the size of the image itself, while changing the canvas size alters the workspace around the photo. Decide first whether you want to send a smaller photo or add margins to fit a specific ratio.

To remove part of the content, use crop; to blur sensitive areas, use region effects; to insert text or a logo, select the corresponding editing tool. After saving, check the resulting image again to ensure it is the desired size and that no parts meant to be hidden or cropped are left.

Examples and Selection Help

Shrinking a 1600px photo to 800px changes the image itself, while adding margins to a square canvas keeps the photo and changes its surroundings. This tool supports cropping and region effects, but it does not automatically crop subjects or remove backgrounds.

Frequently asked questions

Are images sent to the server?

No. They are processed only within the current browser.

Is the original file changed?

No. All results are downloaded as new files.

Can I recover contents obscured by mosaic or blur?

For downloaded PNG, JPG, or WebP files, the effects are embedded into the original photo pixels, leaving no previous pixels of the obscured areas. However, during the editing session before downloading, you can revert to the pre-effect state using Undo.

What formats are supported?

Inputs are JPG, PNG, and WebP; HEIC and HEIF are not supported. Outputs are PNG, JPG, WebP, and GIF.

Can I keep the transparent background?

PNG and WebP maintain transparency, whereas JPG treats it as white.

Why does processing large images stop?

Due to browser and device canvas/memory limits. Please reduce the output size or the number of files.

Can I save at an exact pixel size?

Yes. Set the pixel size in the size panel, then save.

Does this screen open the size panel directly?

Yes. It opens in the resize starting state.

Can I mosaic only a selected area?

Yes. Select the area to cover and apply the mosaic effect.

Does this screen open the effect panel directly?

Yes. It opens in the mosaic starting state.

Can I place text directly on the picture?

Yes. Add the text in the text panel and save.

Is anything inserted automatically on open?

No. Nothing is inserted automatically.

Does making a small photo bigger make it clearer?

Simply increasing the pixel size does not restore details that weren't in the original. Check the text and edges after enlarging.

Is all personal information safe just by applying a mosaic?

You must manually verify the intensity of the effect and the covered area. If your goal is to clearly obscure text in a document, consider the Personal Information Redaction tool and its result verification procedure.
