Image workflow · Practical guide
Resize or compress? Prepare an image that fits
Understand pixels, file size and JPEG quality, then inspect the output before using it in a website or upload form.

Pixel dimensions describe the image width and height. File size describes the number of stored bytes, often displayed in KB. A smaller width does not guarantee a particular file size. Read the destination’s current instructions for format, dimensions and file-size limits; keep your original image.
2. Resize when the dimensions are too large
Our resizer accepts an output width and calculates the height to preserve proportions. A 1200 × 800 image at width 600 becomes 600 × 400 pixels. It exports PNG, which may be larger than a source JPEG. Enlarging an image cannot recover missing detail.
3. Compress when a photograph needs fewer bytes
Open the image compressor and start around 70% JPEG quality. Download and inspect edges, small text and faces at the intended display size. JPEG is lossy and transparent areas become white. A quality setting is not a percentage reduction in file size, and the output can be larger than an already optimized source.
4. Inspect the actual saved file
Check the output dimensions, bytes and extension, then open it in an image viewer. If both dimensions and file size matter, resize first and compress the saved image next. The compressor’s maximum-size mode measures the JPEG against a chosen byte limit, with optional resizing. It does not guarantee an exact size or acceptance by an external form. Check every output against the destination’s rules.
Try the workflow
Start with a small example and check the result before using your own data.
