Image Editing & Conversion Guide
Prepare image files for websites, forms and sharing.
Image tools solve different problems: resizing changes dimensions, compression targets file size, cropping changes framing, and format conversion changes how image data is stored. Choosing the right operation helps preserve the result you actually need.
Resize, crop or compress?
- Resize when a website or form requires a specific width and height. Preserve the aspect ratio unless you intentionally want to stretch the image.
- Crop to remove unwanted edges or focus attention on the subject. Keep the original if you may need the full frame later.
- Compress when the image dimensions are already suitable but the file is too large. Lossy formats may reduce detail; compare the result at normal viewing size.
- Convert format to meet compatibility needs. JPEG is common for photos, PNG supports transparency, and WebP can offer efficient web delivery, but check where the image will be used.
Keep quality under control
Repeatedly saving a lossy image can introduce additional artifacts. Start from the highest-quality original and perform edits in one session where possible. For transparent graphics, confirm that the output format supports transparency.
For web uploads
Use dimensions close to the actual display size, give files descriptive names, and preview them on both desktop and mobile. Avoid enlarging small images expecting genuine detail to return; upscaling creates estimated pixels, not recovered original information.
Privacy reminder
Photos can contain location metadata or reveal private information in the image itself. Before sharing, review the visible content and metadata requirements of the destination. Use only images you own or have permission to edit and publish.
About this guide: This is general practical information. Always review the output and the requirements of the service where you plan to use the file.
