Professional Image Resizer

How to use it

1. Drop, paste or choose one or more images. Each picture appears in the strip so you can select it and compare the original with the result.
2. Pick a sizing method: a maximum file size, exact pixels or print size, a percentage, an aspect ratio, an upscale factor or a ready-made preset.
3. Adjust cropping, padding, rotation, brightness, sharpening or a text watermark if needed, then choose the output format.
4. Download the selected image, or download the whole batch as one ZIP file. Save your settings to reuse them next time on this browser.

Practical tips for plant photos

• For nameplates and gauges, keep enough resolution to read small text; check the result at full size before sending.
• Use the file-size mode when an email system, portal or form limits attachments, for example 500 KB or 1 MB.
• JPG or WebP suit photographs; PNG keeps sharp edges on screenshots, drawings and labels.
• Auto-trim and crop help remove empty background around a part before it goes into a maintenance or inspection report.

Professional, Advanced and Expert levels

• Professional keeps the everyday tools: size and file-size targets, presets, compression, cropping, rotation, watermarks and batch ZIP downloads.
• Advanced adds Lanczos3, bicubic, bilinear and nearest-neighbour resampling, noise reduction, gamma, a drag-to-crop editor, print/DPI checks, PNG optimisation, metadata choices and an image inspector.
• Expert adds perspective correction, content-aware cropping, technical diagnostics, optional on-device AI upscaling, exportable batch profiles and a printable processing report.

Specialist workflows

• Industrial nameplate keeps serial numbers, instrument tags and gauge scales readable.
• Engineering drawing keeps lines and dimensions sharp and saves lossless PNG.
• E-commerce makes square product images on a white background for Shopify and catalogues.
• Web developer makes responsive widths and ready-to-paste picture/srcset code.
