Everything ImgSera can do

Move between JPG, PNG, WEBP, BMP, TIFF and PDF with quality control, presets and a real encoded-size estimate before you commit.

• Six formats, both directions JPG, PNG, WEBP, BMP, TIFF and PDF — including single-image PDF export.
• Quality control Set quality from 1–100 for JPG and WEBP, or pick a preset.
• Built-in presets Web Optimized, E-commerce Product, Email and Print starting points.
• Estimate Output Size See the real encoded size of the first selected image before exporting.

Real-ESRGAN upscaling that enlarges a photo to 2× or 4× using a real neural network running on your own machine.

• 2× and 4× upscaling 2× for everyday use, 4× when you need maximum detail.
• GPU or CPU Accelerates through DirectML on a DirectX 12 GPU, and falls back to CPU automatically.
• Works offline afterwards The model is downloaded once, then every enhancement runs with the network unplugged.
• PNG output Results are written as lossless PNG so upscaling never compounds compression artifacts.

U²-Net subject matting lifts your subject out of the frame with soft, refined edges — useful for product and catalogue shots.

• Subject-aware masking A real salient-object model, not a hard threshold or a chroma key.
• Three output modes Transparent PNG, solid white, or solid black background.
• Refined edges Soft matting keeps hair, fur and fabric from looking cut out.
• Runs locally The model is fetched once on request and then works offline forever.

Resize by percentage or exact pixel dimensions, with aspect-ratio protection and high-quality resampling.

• Percent or exact size Scale everything by a percentage, or pin an exact width and height.
• Aspect-ratio protection Lock the ratio so pictures never get silently stretched.
• Lanczos resampling A high-quality filter that avoids the softness of naive scaling.
• Any output format Resize and re-encode in a single pass, in the format you choose.

The real sample photographs bundled with ImgSera, resized by a percentage or a pinned width — the exact dimension math the Resize page performs, with the ratio always preserved. The on-screen preview is scaled by your browser; the app writes true Lanczos-resampled pixels at the size shown.

Quality-targeted compression that tells you exactly how much space you saved instead of quietly re-encoding.

• Measured savings Original size, new size and percentage saved are reported per batch.
• WEBP defaults WEBP around quality 75–82 is a strong general-purpose web setting.
• Visible quality control Nudge the slider and watch the size estimate move with it.
• Batch friendly Compression runs through the same queue as every other tool.

One of the sample photographs bundled with ImgSera. 1600×1067, encoded to WEBP by ImgSera. The original JPEG is 65 KB on disk.

Each step is a real WEBP encoding written by ImgSera at that quality setting — not a preview. Turn on 1:1 to see exactly where quality gives way.

Build a single, well-formed PDF from many images — or pull images back out of a PDF at the resolution you need.

• Images to PDF Combine many images into one document in a page order you control.
• Page setup A4, A3, A5, Letter, Legal or original size; portrait, landscape or auto; adjustable margins and fit.
• Reorder pages Move pages up and down before you commit to the file.
• PDF to images Render PDF pages to PNG, JPEG or WEBP at 72–600 DPI.

Queue hundreds of files with live progress, and keep control while they run.

• Live progress Filename, operation, output path, status and space saved for every file.
• Pause and resume Pause mid-run; in-flight files finish first, then the queue holds.
• Cancel safely Stopping keeps everything already completed. Nothing half-written is left behind.
• Retry failed only Re-queue just the failures instead of starting the batch over.

Crop toward the detected subject, so faces and products stay in frame instead of drifting to the edges.

• Subject-aware framing Detects the subject and biases the crop window toward it.
• Aspect presets Crop to a target ratio while keeping the subject inside the frame.
• Non-destructive Preview the crop before committing; the source file is untouched.

Look at an image properly before you change it — format, dimensions, size and embedded metadata in one place.

• Format and dimensions Read the real width, height, colour mode and file size of a selected image.
• Metadata at a glance See EXIF details such as camera, exposure and date without opening another tool.
• Actionable recommendations The Inspector suggests which tool suits the image, such as Smart Crop or compression.

What it suggests

• Slight softness detected — try AI Enhance
• Background dominates the frame — Smart Crop can tighten it

Worth knowing: Sharpness is measured on a downscaled copy, so a sharp photograph can still score in the Fair band. The food sample is one: it is in focus, and it scores 55.

Every reading comes from ImgSera’s own quality analysis, run against the sample photographs it ships with. Pick an image and the measurements change.

Chain image operations into a pipeline and run the whole thing in one pass. Build the pipeline visually, or describe what you want in plain language and let Ask Sera draft it.

• Visual pipeline editor Arrange operations in the editor, inspect and adjust each step, then run the pipeline with live monitoring.
• Built-in pipelines Amazon Product, Website Optimized and Product Studio ship ready to run, and stay protected from editing.
• Save your own Build and manage custom workflows that persist between sessions.
• Ask Sera drafts it Describe the result you want; the assistant turns it into a validated pipeline built only from supported operations.

Manage the AI models you use, and keep a local record of the work you have done.

• On-demand models Download or remove models as needed — you are never forced to install weights you will not use.
• Models survive updates Stored outside the application folder, so upgrading never re-downloads them.
• Local history A local log of every batch: when, what, how many files and space saved.
• Clear when you want Wipe the history and thumbnail cache from Settings at any time.
