Over the span of 50 years, my mom and dad traveled the world, capturing their adventures on slides. After my mom passed away six months ago, my sister and I wanted to honor their life together by digitizing those memories so we could share them with our family for generations to come. The task of converting decades of slides felt overwhelming, and we knew we needed a professional. Thankfully, we found Mr. Sharma and his team at eRecordsUSA. They handled our project with great care and attention to detail--cleaning each slide and organizing them into easily accessible folders by month and year. We are beyond grateful for their work and highly recommend eRecordsUSA for any project, big or small.

I contacted the eRecordsUSA team for a project scanning several dozen journals. I was a little nervous at first about shipping irreplaceable personal records for someone else to handle, but from the first call with Pankaj it was clear I was in excellent hands. From start to finish I've never experienced such thoughtful, responsive customer service, and the final color scans I received are sharp, accurate, and perfectly organized. I am thrilled to have over a decade of journals scanned and preserved so beautifully. eRecordsUSA will be my first call for any future digitizing needs.

Pankaj and crew at eRecordsUSA did a beautiful job making scans of our old family archives that span four generations. Now I have thousands of neatly organized .pdf files with crisp & clear scans of my family's handwritten letters, photos, slides, and fragile documents from 100 years ago. I've been daydreaming about this project for over a decade, and I'm very grateful to now have it so successfully completed.

I had an unusual requirement that involved scanning a 4' by 8' document on a roll. The staff did an excellent job capturing all the information, using several approaches to ensure the best reproduction. I'm grateful for the time the staff took to explain the options. I'm very pleased with the result.

My experience with E-Records USA and their dedicated team was beyond reproach. They kindly hand held me through a long term project of digitizing every photo album, framed photo, and CD accumulated for over 30 years. They showed me what they could do back in 2022 and waited patiently until I was fully ready to make the project happen in 2024. I know they have many other clients, but I always felt like I was priority and important. They never shied away from all my questions, concerns, and fairly constant stream of emails. They patiently took me through the whole project and kept me updated informed at every step. This was not inexpensive, but the peace of mind I have that all our memories are now safely stored in a few places and can be accessed by my family at any time is worth it. And I freed up many, many boxes and therefore shelves full of bulky photo albums and framed pictures. It was something I had wanted to do for several years and I am so glad I found a company that was so trustworthy and caring about these invaluable memories. I would work with them in the future without question. They went above and beyond.

Had them digitize my grandmother's daily diary from 1912. It was in a bound journal. Files came out great. My cousins were thrilled to be able to read it. Was done in only a few short days.

My family and I feel so fortunate to have found Pankaj and eRecords USA. We have dozens of family photo albums and with three siblings there wasn't going to be a good way to split them up. The photos were in albums with plastic sheet covers and many of them had writing on the back and/or on the side of the picture on the album itself. We wanted to preserve the handwriting and information about the photo and the actual photos. Before consulting with Pankaj my highest hope was to get the photos scanned. What he was able to do went above and beyond what I had hoped for. Not only did he create a PDF each album, preserving the order of the photos and all of the handwriting, but he then provided individual scans of every single photo AND the information on the back at a resolution quality that will allow us print the photos in the future. Not a single photo was damaged and some of them were in albums for over 70 years. I can't imagine the patience and perseverance it took to gently handle these hundreds of photos. In addition to the quality of the work, the communication, customer service, delivery times, accuracy of pricing and transparency of the process were top notch. We are so grateful to have these memories preserved for ourselves and future generations. Thank you Pankaj and team!
