![]() ![]() events: - http: path: /resizer method: GET #. The Lambda function only requires getObject & putObject permissions to our specific S3 bucket. In a production environment, I recommend following the principle of least privilege and set more restrictive access. Only use AmazonS3FullAccess policy for a quick demonstrative setup. View and copy the API Key & Secret to a temporary place, we'll need them for the Lambda config. Go to Users and click "Add users" > pick a username that'll be easier to remember > check "Programmatic access"Ĭlick "Next" to go through to the Permissions page, click on "Attach existing policies" directly, and select AmazonS3FullAccess* Log in to the AWS account and go to the Identity & Access Management (IAM) We'll start by creating an IAM user that will allow our Lambda function to put the resized images on S3. Architecture overviewġ) The user requests a resized image via Cloudfront (if the asset exists it will be returned and everything stops here)Ģ) Cloudfront requests the asset from the S3 bucket (using a website endpoint)ģ) Because the asset doesn't exist the browser will be temporary redirected (307) to the API Gateway endpointĤ) API Gateway triggers the Lambda functionĥ) The Lambda function downloads the original image from the S3 bucket, resizes it, and uploads the resized image back into the bucket with the requested keyĦ) The API Gateway returns a permanent redirect (301) to the newly created asset Cloudfront URL The Setup Why process and store the assets that may not even be accessed by users? I'm going to process them on the fly (lazily), a resized image will only be created if a user requests that specific size. There are about 300k images to be resized, running a batch process to resize all the images into new dimensions will be time-consuming and quite costly. It does the job, but wastes server resources. The old logic works like this: the user uploads product photos > the app server creates predefined image sizes using GD Library > uploads into an S3 bucket. The new design features larger images, it will display thumbnails with different proportions and also makes use of "srcset" attribute to display responsive images. ![]() At the time of writing, the marketplace has close to 40k active products for sale, not including the drafts, products pending approval, or the sold ones. Compressing images with the website is free for everyone and we like to keep it that way! If you like TinyPNG please contribute by making a donation.I've been working (on the side) lately on a redesign for the first SaaS I've built, a handmade marketplace for Romania's market. In 2014 we added intelligent compression for JPEG images and in 2016 we added support for animated PNG. We created TinyPNG in our quest to make our own websites faster and more fun to use with the best compression. Why did you create TinyPNG?Įxcellent question! We frequently use PNG images, but were frustrated with the load times. It allows you to scale, preview and save compressed PNG and JPEG images straight from Photoshop. You can also install the TinyPNG Photoshop plugin. We’ll convert them to tiny indexed PNG files. You can use Save for Web to export your images as 24-bit transparent PNG files and upload them to TinyPNG. With other versions it is impossible and Photoshop CS5 cannot even display them properly. What about Photoshop?Įxcellent question! Only Photoshop CC 2015 or newer can save images as indexed PNG files with alpha transparency. If you want to create and compress stickers under 500 KB take a look at the iMessage Panda sticker example on Github. Only Internet Explorer does not support the format yet.Īpple added animated stickers to iMessage with the release of iOS 10. Binary transparency without any workarounds! Is it safe to use animated PNG?Įxcellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. With TinyPNG the background becomes transparent again. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. Is it supported everywhere?Įxcellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you. ![]() In the above image the file size is reduced by more than 70%. The result better PNG files with 100% support for transparency. All unnecessary metadata is stripped too. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images. File size 57 KB vs Shrunk transparent PNGĮxcellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined. ![]()
