Bulk uploads and downloads. What We Don't Like Accepts uploads from your device only, not a cloud storage service or a URL. Few output formats. Has an undisclosed dimensions limitation. Image Candy is a website with lots of free online tools, one of which is an image converter. It supports tons of input formats and will even convert images that are up to a whopping 2 GB in size.

Just upload one or more photos to the site, rotate any of them if necessary, and then pick from any of the supported output formats. You can download each converted file individually or together in an archive. This is an online converter, so it works from any operating system. Your uploads are deleted automatically after two hours. Visit Image Candy 02 of 11 XnConvert What We Like Converts between lots of image file formats. Can convert multiple images at once. Lots of advanced settings you can customize. Converts images on Windows, Linux, and macOS. Portable option is available. What We Don't Like Might be too advanced if all you need is a simple image converter. The software must be downloaded to your computer before you can use it. XnConvert is the Swiss Army knife of image converters. It can convert any of around 500 image formats to your choice of around 80 others. If you have a rare image format that you can't open, this program can probably convert it. It also supports batch conversion, folder imports, filters, resizing, and several other advanced options.

The publisher of XnConvert also has a free command line based, dedicated image converter called NConvert, but XnConvert is much easier to use. It runs on Windows, Mac, and Linux. There's a portable option on the download page, available for both 32-bit and 64-bit versions of Windows and Linux. Download XnConvert 03 of 11 Coolutils What We Like Runs online, so you don't have to download the converter tool. You can resize and rotate the image before converting it. Lets you download the image right away from the web page. What We Don't Like Can convert only one image at once. Requires uploading and downloading the image. Doesn't show a preview of the picture (useful when rotating). Coolutils is an image converter that exists completely online, no download required. Unlike some online converters, this one does the converting for you in real-time—no waiting on an email link. Input Formats: BMP, GIF, ICO, JPEG, PNG, and TIFF Output Formats: BMP, GIF, ICO, JPEG, PDF, PNG, and TIFF There is a file size limit on the original file you upload, but we can't confirm the specific limit. Our tests indicate that the limit is somewhere between 35 MB and 40 MB. One thing we like about this option is that it lets you rotate and resize an image before you convert it. Then again, it isn't as useful as it could be because it doesn't show you a preview of what the rotated image will look like when converted. Since this method works through a web browser, you can use it with nearly any operating system, like Windows, Linux, and Mac. Visit Coolutils 04 of 11 Zamzar What We Like Supports bulk conversions. Works online, so you don't need to install anything. Images can be as big as 50 MB. One of the easier-to-use image converters. What We Don't Like Converts a maximum of two images per session and 24 hours. Images are downloaded individually (even if you convert more than one). Our Review of Zamzar Zamzar is an online image converter service that supports most common photo and graphic formats and even a few CAD formats. You can download the converted file from an email or wait on the download page for the links. A file can be uploaded from your computer, a file storage service you use (Dropbox, Google Drive, etc.), or from another website via its URL.

Visit Zamzar You can use Zamzar to convert not just images but also documents, audio, video, eBooks, and more. See all the formats supported by Zamzar. 05 of 11 FileZigZag What We Like Really easy to use. Works from any web browser in any operating system. Converts images as large as 150 MB (if you log in). Supports bulk uploads, conversions, and downloads. What We Don't Like Conversions are sometimes slow. Limits free users to 10 conversions per day.

Just upload the original image, choose the desired output, and then wait for the download link to appear on the page. Input Formats: AI, BMP, CMYK, CR2, DDS, DNG, DPX, EPS, GIF, HEIC, ICO, JPEG, JPG, NEF, ODG, OTG, PAM, PBM, PCX, PGM, PNG, PPM, PSD, RGB, RGBA, SDA, SGI, SVG, SXD, TGA, TIF, TIFF, XCF, and YUV Output Formats: AI, BMP, CUR, DPX, EPS, GIF, ICO, JPEG, JPG, PAM, PBM, PCX, PDF, PGM, PNG, PPM, RAS, SGI, SVG, TGA, TIF, TIFF, and YUV See every the file conversion you can make at FileZigZag from the Conversion Types page. It also supports documents, audio, video, eBooks, archives, and web pages. Just like any online file converter, you have to, unfortunately, wait for the website to upload the file and then wait again for the download link (which could take a really long time as you wait in the queue). However, since most images are fairly small, it really shouldn't take that long altogether. Visit FileZigZag 06 of 11 Adapter What We Like Very minimal and easy-to-use interface. Conversions are available instantly. You don't have to upload the images anywhere. Supports bulk conversions. Works on Windows and macOS. Installs quickly.

Download Adapter 07 of 11 Resizing.app What We Like Works in your browser. Supports common file formats. Includes resizing options. No intrusive ads. What We Don't Like Relatively short list of input and output formats. Limited to converting one file at a time. The optimizer function doesn't show how well it's working. Despite the name, Resizing.app doesn't just support resizing your photos, but also cropping and, of course, converting. Input Formats: PNG, JPEG, BMP, TIFF, HEIC, GIF, and WEBP Output Formats: JPG, PNG, WEBP, BMP, and TIFF Although few formats are supported, this tool makes up for it in its handy resize options. You can crop the picture or resize it to any custom dimensions. There's also a built-in optimizer that can help reduce the file's size. This is a website, so it works from any web browser. Visit Resizing.app 08 of 11 Media.io What We Like Unique input formats. Supports cloud storage services. Unlimited file size limit. Supports bulk uploads.

Input Formats: JPG, PNG, BMP, GIF, and TGA Output Formats: JPG, PNG, BMP, GIF, TGA, and PDF We like this program because it's very simple to use, supports popular image formats, and includes some additional features you may not find bundled in with other image converters. Free Image Convert and Resize is said to run on Windows 11, 10, 8, 7, and XP. Download Free Image Convert and Resize The installer tries to add a few additional programs to your computer that you don't need to have for the image converter to work, so feel free to skip over them if you wish. 10 of 11 PixConverter What We Like Walks you through a step-by-step wizard. You can adjust the output quality for the images. Lets you resize and rename the images. Can convert more than one image at once. What We Don't Like Works on Windows only.

Input Formats: JPG, JPEG, GIF, PCX, PNG, BMP, and TIF Output Formats: JPG, GIF, PCX, PNG, BMP, and TIF This is a nice converter tool if you deal with these formats and would rather not use an online option. Windows 8, Windows 7, and Windows Vista are the only versions of Windows that are officially supported, but PixConverter works equally well in Windows 10 and probably other versions, too. Download PixConverter 11 of 11 SendTo-Convert What We Like Lets you convert images very quickly. You get to customize all the conversion settings. Supports popular image file formats. What We Don't Like Doesn't support image file formats beyond the few popular ones. Outdated; last update was 2015. Works for Windows users only. SendTo-Convert is an awesome image converter. The program can be automated to the point that you simply have to right-click one or more images and choose Send to > SendTo-Convert to convert them. This means you can set the default output format, quality, size option, and output folder to quickly convert images without having to open the program. Input Formats: BMP, PNG, JPEG, GIF, and TIFF Output Formats: BMP, PNG, JPEG, and GIF This download link takes you to a page that has several other programs listed, the bottom one being for SendTo-Convert.
