Which tool to use for each job

8 min read · PixTodo

You arrive with a photo and a goal, not with a tool name. This guide starts from the job (“I want to do this”) and drops you on the page that solves it. All 31 PixTodo tools run in your browser: your image never leaves your browser.

1. I want to send photos in chat without them weighing a ton

Start with the general compressor (quality or target KB) or, if they are already JPEG, compress JPG. If the photo is huge in pixels, resize first: fewer pixels, less weight — the same logic as the rest of the suite.

2. A form asks for an exact maximum file size

Guesswork will not cut it. Use target-size mode: 100 KB, 50 KB, 20 KB or 200 KB. Each page tunes quality and, if needed, dimensions until the file fits the limit.

3. I publish screenshots or graphics on the web

For PNG, compress PNG leaves screenshots a fraction of the weight and keeps transparency. The biggest jump is usually PNG→WebP (up to 90% smaller per the tool itself). If you still do not know the output format, the general converter does WebP, JPG or PNG in batches.

4. I want camera photos lighter on the web

Convert JPG to WebP with JPG→WebP: at equal quality, 25–35% less weight. That is the shortcut when the destination is a modern site, not a legacy form.

5. I got a format my software will not open

WebP→JPG for universal compatibility; WebP→PNG if you need lossless editing with transparency; AVIF→JPG when the modern file opens nowhere; GIF→JPG if you only want the still frame.

6. I have an SVG logo (or need a favicon, Base64 or palette)

SVG→PNG rasterizes to the size you set. From a logo you can also generate a favicon (ICO, PNG, manifest), get an image as Base64 for embedding, or extract colors as HEX, RGB or CSS variables.

7. I want to strip location or censor before publishing

Remove metadata deletes EXIF, GPS and IPTC without recompressing. If the sensitive bit is in the pixels (faces, plates), pixelate it. To sign or protect a batch, add a watermark with text in bulk.

8. Crop, straighten or make a round avatar

Crop (free or fixed ratio), rotate and flip by 90° or mirror, and circle crop with a transparent background for avatars.

9. I want to change the look: brightness, B&W or sepia

Filters and adjustments cover brightness, contrast and saturation. For the classic look alone, go straight to black and white or sepia.

10. Several photos into a PDF, or swap PNG and JPG

JPG to PDF merges one or more images into a PDF. PNG→JPG when you need smaller files to share; JPG→PNG when you want the lossless format for further editing.
