Shrink a photo for email or upload
Phone photos are 5-10 MB each. Email and web forms typically cap at 1-2 MB. Compress brings the file under the limit without visible quality loss.
Compress Image →Free Online Image Tools
35+ tools. All browser-based, no uploads, no account needed.
Image editing online used to mean choosing between a heavyweight desktop install (Photoshop, GIMP) and a single-purpose website that only does one operation at a time. The tools below cover the editing, optimisation, format conversion, and AI-powered work people actually do day to day: resize a photo for a website, compress a screenshot for email, remove a background for a product shot, convert HEIC to JPG so Windows can open an iPhone photo. They all run in the browser using HTML5 Canvas, jSquash, and on-device ONNX models, so nothing about your photo ever reaches an external server.
The library covers four overlapping needs: edits that change the pixels (crop, resize, rotate, add text), optimisations that change the file (compress, remove background, upscale), format conversions, and filters that change the look (grayscale, sepia, blur, sharpen, colour adjustments). Each tool page explains what its underlying algorithm does and when to reach for it instead of a similar-sounding alternative.

Common workflows
Real situations these tools were built for.
Convert iPhone HEIC photos to JPG
iOS saves photos as HEIC by default. Windows, older Macs, and most websites cannot open them. Convert in bulk to JPG before sharing.
HEIC to JPG →Remove a product background
For an e-commerce listing, a presentation, or a transparent logo cutout. The AI model isolates the subject without manual masking.
Remove Background →Resize a photo to exact pixel dimensions
For a passport application, a website banner, or a printed certificate, the platform usually requires a specific pixel size.
Resize Image →Stamp a date on a paper-trail photo
For inspection reports, time-and-date proof, courier evidence: burn an exact timestamp into the bottom corner of the photo.
Add Timestamp →Generate a complete favicon pack
For a new website, get every size modern browsers and PWA installers ask for (16/32/180/192/512) from one source image, plus the HTML snippet.

Tools that look alike but solve different problems.
Compress Image vs Resize Image
- Use the first when
- You want the same pixel dimensions but a smaller file. Compress trades a small amount of visible quality for big size savings.
- Use the second when
- You want different pixel dimensions. Resize physically shrinks the image, which both makes the file smaller and forces a specific width or height.
Upscale Image vs Sharpen Image
- Use the first when
- The source is low resolution and you need it bigger. The AI model reconstructs plausible new texture at 4× the original size.
- Use the second when
- The source is already the right size, just slightly soft. Sharpen enhances existing edge contrast but cannot recover missing detail.
Grayscale vs Black & White
- Use the first when
- You want a smooth tonal range with continuous mid-greys, the look of a soft cinematic photo.
- Use the second when
- You want graphic punch with deep blacks and bright whites, the look of an editorial or magazine front page.
JPG to PNG vs Image to JPG
- Use the first when
- You need lossless quality for further editing, or transparency support (e.g. logos, screenshots).
- Use the second when
- You need smaller file size and the image is a photograph where the eye will not notice JPG compression.
Crop Image vs Resize Image
- Use the first when
- You want to remove unwanted areas of the photo and keep only the part that matters. Aspect ratio changes.
- Use the second when
- You want the same composition at a different size. Aspect ratio stays the same; only the pixel dimensions change.

How your files are processed
The image tools here run on your device in the browser: compressing, resizing, cropping, rotating, format conversion (including HEIC to JPG), and even the AI background remover and upscaler, which download a model once and then run locally. Your photos are not uploaded to do this work, which is useful for personal pictures and unpublished product shots. If a specific tool ever needs the server, its page will tell you before you start.
See our Privacy Policy for full details.
Tips for best results
- Resize before you compress: dropping a 4000px photo to the size it will actually display often shrinks the file more than compression alone, with no visible quality loss.
- To hit a target like 100 KB or 200 KB for an upload form, use Compress Image and check the live size readout before downloading.
- Keep PNG for graphics, logos, and anything with transparency; use JPG for photographs: converting a photo to PNG usually makes it larger, not smaller.
- For e-commerce, remove the background and export on white or transparent so the product fills the frame consistently across a catalog.
- HEIC from an iPhone will not open on many sites: convert to JPG first so it is universally viewable.
Frequently asked questions
About this whole category. For tool-specific questions, see each tool page.
Are my photos uploaded to your servers?
No. Every image tool here runs entirely in your browser using HTML5 Canvas and on-device JavaScript libraries. Your photo is read by the page once, processed locally, and offered for download. The AI-powered tools (background removal, upscaling, watermark removal) run an on-device ONNX model: the photo and the model weights both stay in the browser tab, with no API call made.
What image formats do these tools support?
JPG (.jpg/.jpeg), PNG, WebP, BMP, TIFF, GIF, HEIC/HEIF, and SVG. The exact set varies per tool: a compressor handles all formats, a HEIC-to-JPG converter only reads HEIC, and so on. Each tool page lists supported formats explicitly. AVIF support is rolling out as Safari extends its decoder coverage.
Do the AI tools work without internet?
After the first visit (which downloads the model weights), yes. Background removal, AI upscaling, and watermark removal use models that download once and cache in your browser. Subsequent runs on the same device work offline. The first run does need internet to fetch the 5-80 MB model file.
Will the output be watermarked or downscaled?
No. Output images keep the original resolution unless you explicitly resize them, and no watermark is added. This is the main difference between this tool collection and free tiers of Smallpdf, Canva, Fotor, or Pixlr, which often add branding to free exports.
How do these tools handle EXIF data and GPS metadata?
By default, the editing tools strip EXIF metadata when re-encoding, which is what most people want when sharing photos publicly: EXIF includes GPS coordinates, exact timestamps, and device serial numbers. The View Image Info tool lets you inspect EXIF before stripping it, and the per-format converters (Image to JPG, JPG to PNG) offer a keep-metadata option.
Can I batch-process many photos at once?
Yes, for the conversion and compression tools. Drop a folder of mixed-format images into Bulk Convert Images, pick a target format, and download the result as a single ZIP. For editing operations (resize, crop, watermark), most tools accept multi-file uploads and apply the same operation to each photo.
How do the AI models compare to Adobe Express or Canva?
The background-removal and upscale models here are open-source ONNX networks (RMBG-1.4 and Real-ESRGAN respectively). They are competitive with the proprietary cloud APIs Canva and Adobe use, with the key difference that they run entirely on your device. That means no API quota, no monthly cost, and no requirement that the photo leave your machine. For commercial cases involving thousands of images, a dedicated paid API may still be more practical.
Why use browser-based image tools?
