I require assistance in optimizing various image files to be used for an upcoming promotion on my website and social media platforms. There are over 50 images in total, mostly product photographs and lifestyle shots, that need to be reviewed and resized as required without compromising on quality. Some may need to be enlarged to at least 1500 pixels on the longest side to allow for flexible usage across different devices and formats. Others can be scaled proportionately. All file types need to be converted to JPEGs with an image quality of 70-80%. Metadata should be checked and all EXIF and IPTC data cleaned up. A quantitative and qualitative analysis will also be done to ensure none of the visual elements are distorted or pixilated after resizing. The final images should be compressed and optimized for quick page loading without sacrificing clarity. Knowledge of Adobe Photoshop or similar image editing software is essential. Experience with batch processing techniques and effective compression methods would be an added advantage. Please provide samples of your previous work along with your pricing and turnaround time for this project. I look forward to receiving competitive bids from talented graphic designers.
