Resize Image Online — Free Image Resizer to Exact Pixels

Upload your image, enter the desired dimensions, and click resize. This online image resizer preserves quality and helps create images for social media, websites, and print with precise dimensions. Supports JPG, PNG, WEBP, GIF, SVG formats.

Yes. Keep the aspect ratio locked and enter one dimension to automatically calculate the other. This is useful for creating images that fit specific layouts without distortion.

We support JPEG, PNG, WebP, GIF, and TIFF formats. The output format will be the same as the input format, preserving quality and transparency.

Making an image smaller (downscaling) keeps it sharp — we use high-quality resampling so detail stays clean. Making an image larger (upscaling) is different: there are no extra pixels to add, so the software interpolates and the result can look soft or blurry. To enlarge a photo without that softness, use our AI Upscaler, which reconstructs detail instead of stretching it.

Yes. Enter the exact pixel dimensions you need for a print-ready image. Note that print sharpness depends on pixel count, not just the DPI tag: for an 8x10" print at 300 DPI you need roughly 2400x3000 pixels. If your source is smaller than that, enlarge it first with our AI Upscaler so the print stays crisp.

Yes. Resizing happens on our secure servers; uploads are encrypted in transit and removed under our Security policy. Downloads have no watermark.

Resizing changes the pixel dimensions (width × height), which usually lowers the file size too — but if you need to hit a specific target like 100KB, 50KB or 20KB, use the Compress Image tool instead. It optimizes the file size directly without changing the dimensions.

Resizing scales the whole image to new dimensions, while cropping cuts away part of the image to keep only the area you want. To trim or recompose a photo, use the Crop Image tool (or Circle Crop for round profile pictures), then resize the result here if you also need exact dimensions.

Click one of the percentage presets — 25%, Half (50%), 75%, Original (100%) or 2x Enlarge — and the tool scales the target dimensions relative to your uploaded image's own size, so you don't have to calculate exact pixel numbers yourself.

Yes. Social media presets fill in exact pixel dimensions for Facebook (profile, cover, post, event), Instagram (post, story), Twitter and YouTube in one click, and Passport presets cover the common 2.5x3.5cm, 3.5x3.5cm and 3.5x4.5cm photo sizes — no manual measuring needed.

Both fill the empty space when your target dimensions don't match the photo's original aspect ratio, so the subject isn't cropped or stretched. Color pads with a solid color you choose from the color picker or swatches; Blur pads with a softened, zoomed copy of the photo itself, with a Blur Intensity slider (5 light to 50 heavy) controlling how soft it looks. Both are options in the Background tab, alongside Gradient, Designs and Photo, and only one is active at a time.

The Quality slider (10-100%) controls compression on the resized output — higher keeps more detail but produces a bigger file. Output Format lets you switch the result to JPEG, PNG, WebP or GIF independently of the source file's format, so you can resize a large PNG and export it as a smaller JPEG in the same step.

Pick the Instagram Post preset (1080x1080), choose Blur in the Background tab so any mismatch between your photo's aspect ratio and the square target pads instead of cropping the subject, set Quality around 85-90, and choose JPEG as the Output Format for a fast-loading upload.

Yes. Batch mode applies the same width, height or percentage settings to up to 60 images with Premium or 200 with Pro, then returns one ZIP. A single full-size resized result can be previewed and downloaded without creating an account.

Bulk mode — a Premium feature — resizes many images in one go: upload the set, choose the dimensions or percentage once, and download all the resized copies as a single ZIP. A bulk pass like this is handy for product photos, galleries and email assets that all need the same size.

File size in KB depends on both pixel dimensions and compression. Reducing the width and height here shrinks the file substantially, and lowering the quality setting reduces it further. If you need to hit an exact number, run the resized image through our image compressor, which accepts a target file size in KB.

Yes — pick resize by percentage and scale the image up or down proportionally, for example 50% to halve both dimensions. It keeps the aspect ratio automatically, so nothing looks stretched. Use custom dimensions instead when a platform asks for exact pixels, like 1080x1080 or 1280x720.

Yes — Pixoate supports batch and bulk processing. Switch to Batch mode, add up to 60 images on Premium or 200 on Pro, set your options once, and every image is processed with the same settings before you download a single ZIP. Bulk processing is a Premium feature; the output uses the same quality and settings as single mode.

Yes — with bulk processing you configure the settings a single time and they apply to every item in the batch — up to 60 images on Premium or 200 on Pro. There is no need to repeat the setup per item, and Temporary uploaded and generated files are processed securely and deleted automatically.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking image gets refused.

Cropping, rotating, resizing and framing keep your original pixels — quality loss almost always comes from somewhere else. The two usual causes are enlarging a small image past the resolution it actually has, and re-saving a JPG over and over, because each save throws away a little more. Start from the largest original you still have, and export PNG when the image contains text, screenshots or flat color.

Resize Image supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Premium supports batches of up to 60 files, with the applicable plan limits shown before processing.

No — Resize Image runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.

This tool resizes pictures such as JPG, PNG, WebP and GIF files, not PDF pages. To make a PDF file smaller, use Compress PDF, and to trim the margins of its pages, use Crop PDF. For a picture inside a PDF, extract it with Extract Images from PDF, resize it here, and use Image to PDF if you need a new PDF from it.

Upload the picture, open the Size tab and type a new Width (px) or Height (px), or pick a percentage or a ready-made size. With Maintain aspect ratio ticked the other number follows. Select See result, then download the resized file. Nothing is stretched unless you untick the lock.

Switch to Batch mode, add your pictures and pick one setting: a pixel size gives every picture the same width and height, and a percentage scales each from its own size. Batch mode is a paid feature, and the results come back in one ZIP.

Yes. This online photo resize tool is free for one picture at a time, and the resized file is saved without a watermark. Batch mode for many pictures is a paid feature, and on a free download the Gradient, Designs and Photo background fills come at web size.

Enlarging cannot add detail that the picture never captured, so a big enlargement looks soft. To increase photo size without losing quality you can see, keep it modest with the 2x (200%) Enlarge button, or use Image Upscaler, which adds detail with AI. Check an upscaled result at full size, because generated detail can differ from the original.

You cannot set an exact KB size here, but a larger width and height, or a higher Quality setting with JPEG or WebP output, usually produces a larger file. To bring a file down to a size target instead, use Image Compressor.

Turn off Maintain aspect ratio on the Size tab, then type the width and height you want. With the lock off, the picture is stretched to exactly that size, which distorts faces and circles. To make a picture wider without distortion, keep the lock on and let a blur, color or Extend background with AI fill the extra space.

Keep Maintain aspect ratio ticked on the Size tab, so changing one number moves the other. When the new size has a different shape from the photo, the whole picture is fitted inside it and the leftover space is filled from the Background tab, with a blur by default.

Yes, for supported shapes. With Maintain aspect ratio on, the image resizer AI option, Extend background with AI, continues the scene into the new size instead of adding bars. It works for 1:1, 4:5, 5:4, 9:16, 16:9, 3:4 and 4:3 frames. Free downloads of AI results come at web size, so review the generated areas before you use the picture.

It edits the size and shape of a picture and the fill around it, and nothing else. Upload the picture, set the size on the Size tab, check the live preview and download the file. For retouching, text and layers, open the Photo Editor instead.

Type the same width and height for every picture on the Size tab and keep Maintain aspect ratio ticked, so each photo is fitted inside that size and the leftover space is filled from the Background tab. Untick the lock to stretch instead. For a whole set at once, use Batch mode, a paid feature.

Upload the BMP, type the new Width (px) or Height (px) on the Size tab and select See result. The resized file is saved as a JPEG unless you choose PNG, WebP or GIF under Output Format on the Output tab. There is no BMP output on this page.

JPEG is the default Output Format unless you upload a GIF. Open the Output tab and choose PNG or WebP before you run the resize, because JPEG cannot keep transparent areas. A PNG of a photograph is usually larger than a JPEG of it, so keep JPEG when you do not need transparency.
