Frequently asked questions

What does Image Compressor do?

Shrink an image by re-encoding to JPEG or WebP at a chosen quality (with optional resize) and see the size saved.

When would I actually use this?

Preparing an image for somewhere specific: cropping to an aspect ratio, resizing under an upload limit, straightening a photo, or shrinking a file that is too heavy.

What is the most common mistake?

Enlarging a small image and expecting detail. Upscaling invents pixels from the ones already there; it can smooth an image but it cannot add information that was never captured.

How is Image Compressor different from Add Line to Image?

They sit next to each other but answer different questions: Add Line to Image is the one to open when you need it to draw freehand lines on an image — pick color, width and style, undo, and download — all in your browser. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Add Text to Image is the closest one after this: Overlay text on an image with your choice of font, size and color, drag it into place and download.

What else is worth having open alongside it?

Image Censor and Image Cropper — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Editing goes through the browser's canvas, and the output carries no watermark. Re-saving a JPEG re-compresses it, so work from the original rather than from an already-edited copy.

Here's how to shrink an image the smart way — format, resolution and compression level — without visible loss.How-toWhat EXIF Data Reveals, and How to Strip It ProperlyA photo file carries coordinates, an exact timestamp, the device and lens, and on some cameras a serial number. Here is what is actually in the block, what stripping does and does not fix, and how to verify it worked.ExplainerWatermarking: What It Protects, and What It Does NotA visible mark lives in the pixels, so it survives every copy — and degrades the image for every honest viewer at the same time. Measured: what a corner mark costs, what a tiled mark costs, and how each compares to metadata credit, Content Credentials and invisible watermarking.GuideFavicons: What Sizes You Actually Need in 2026Five files cover every consumer that exists: the tab, the bookmark, the pinned tile, the Android home screen and the iOS home screen. The twenty-file lists are a dead browser matrix — with measurements showing what a 16-pixel icon can and cannot hold.ComparisonWebP vs JPG vs PNG: Which Image Format Should You Use?JPG, PNG and WebP each win in different cases. Here is when to use each for the best balance of quality, file size and compatibility.ExplainerStripping Photo Metadata: What Actually Comes OffA JPEG can carry six separate metadata blocks, not one. We built a file holding all of them — coordinates, camera serial, a hidden thumbnail, XMP, IPTC, a comment — pushed it through the cleaner, and read the output byte by byte to see what survived.
